“Blessed are the peacemakers, for they shall be called sons of God.”
With each beatitude, another nail is driven into a coffin. Inside the coffin lies the corpse of a false understanding of salvation. The false understanding says that a person can be saved without being changed. Or, that a person can inherit eternal life even if his attitudes and actions are like the attitudes and actions of unbelievers.
Get a New Heart
One after the other, the Beatitudes tell us that the blessings of eternity will be given only to those who have become new creatures. For example, “Blessed are the merciful, for they shall obtain mercy. . . . Blessed are the pure in heart, for they shall see God. . . . Blessed are the peacemakers, for they shall be called the sons of God.”
If we don’t obtain mercy, we receive judgment. If we don’t see God, we are not in heaven. If we aren’t called the sons of God, we are outside the family. These are all descriptions of final salvation, and it is promised only to the merciful, the pure in heart, and the peacemakers.
Thus, the Beatitudes are like long spikes holding down the lid of the coffin on the false teaching that says if you just believe in Jesus, then you will go to heaven — whether or not you are merciful, or pure in heart, or a peacemaker. From beginning to end, the Sermon on the Mount cries out, “Get yourself a new heart! Become a new person! The river of judgment is at the door!” You recall the words of verse 20: “Unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven” (Matthew 5:20).
At the very end of the sermon in Matthew 7:26, the Lord calls out over the crowds,
“And everyone who hears these words of mine and does not do them will be like a foolish man who built his house on the sand. And the rain fell, and the floods came, and the winds blew and beat against that house, and it fell, and great was the fall of it.”
In other words, a life of disobedience to the Beatitudes and to the Sermon on the Mount will not stand in the judgment no matter what we believe.
Obedience Is Not Optional
I was convicted this past week that I have probably not treated this dimension of the Beatitudes with as much earnestness and seriousness as I should, and that the care that I have for your eternal good has not shown itself as genuinely as it must. My conscience was pricked in reading an old book by Horatius Bonar to pastors in which he said,
Our words are feeble, even when sound and true; our looks are careless, even when our words are weighty; and our tones betray the apathy which both words and looks disguise. (Words to Winners of Souls, 55)
“Jesus cries from beginning to end, ‘Get yourself a new heart.’”
I want to impress upon your consciences this morning with as much earnestness as I can that Jesus is not making optional suggestions in the Beatitudes, and this sermon is not a series of suggestions on how to make the world better. On the contrary, Jesus is describing the pathway to heaven, and this sermon is a message from God to urge you to get on that pathway and stay on that pathway so that you can be called sons of God at the last judgment.
That is what is at stake this morning. If you are on the narrow path, which leads to life, my purpose is to help you stay on it. And if you are still in the broad way that leads to destruction, my purpose is to direct you to the path of life.
True Children Resemble Their Father
When Jesus says, “Blessed are the peacemakers, for they shall be called the sons of God,” he is not telling us how to become a son of God. Rather, Jesus is simply saying that sons of God are, in fact, peacemakers. People who are peacemakers will be recognized as the sons of God at the judgment and welcomed into the Father’s house.
If we want to see how to become a son of God we can look at John 1:12 and Galatians 3:26. John 1:12 says, “To all who received him [Jesus], who believed in his name, he gave the right to become children of God.” And Galatians 3:26 says, “For in Christ Jesus you are all sons of God, through faith.” In other words, we become sons of God by trusting in Christ for our forgiveness and hope.
Jesus Made Peace
Jesus says in Matthew 5:9 that people who have become sons of God have the character of their heavenly Father. We know from Scripture that the heavenly Father is a “God of peace” (Romans 16:20; 1 Thessalonians 5:23; Hebrews 13:20), that heaven is a world of peace (Luke 19:38), and most important of all, that God is a peacemaker (2 Corinthians 5:19; Colossians 1:20).
“God was in Christ reconciling the world to himself, not counting their trespasses against them” (2 Corinthians 5:19). “He made peace by the blood of the cross” (Colossians 1:20). Even though by nature we are rebels against God, have committed high treason against him, and are worthy to be eternally court-marshaled and hanged by the neck until dead, nevertheless, God has sacrificed his own Son and now declares amnesty free and clear to any who will lay down their arms of independence and come home to faith.
God is a peace-loving God, and a peacemaking God. The whole history of redemption, climaxing in the death and resurrection of Jesus, is God’s strategy to bring about a just and lasting peace between rebel man and himself, and then between man and his fellow man. God’s children have the character of their Father. What he loves, they love. What he pursues, they pursue. You can know his children by whether they are willing to make sacrifices for peace the way God did.
By the sovereign work of God’s grace, rebel human beings are born again, and brought from rebellion to faith, and made into children of God. We were given a new nature, after the image of our heavenly Father (1 John 3:9). If he is a peacemaker, then his children, who have his nature, will be peacemakers too.
The Spirit of God Is the Spirit of Peace
To put it another way, as Paul says in Galatians 4:6, “because you are sons, God has sent forth the Spirit of his Son into our hearts, crying, ‘Abba! Father!’” He also says in Romans 8:14, “For all who are led by the Spirit of God are the sons of God.” Being led by the Spirit always includes bearing the fruit of the Spirit. And the fruit of the Spirit is peace.
So you see why it must be so — the children of God must be peacemakers. It is by the Spirit of God that we are made children of God, and the Spirit of God is the Spirit of peace. If we are not peacemakers, we don’t have the Spirit of Christ.
So we do not earn or merit the privilege to be called sons of God, rather we owe our new birth to the sovereign grace of God (John 1:13). We owe our faith to the impulses of the new birth (1 John 5:1) and receive the Holy Spirit by the exercise of this faith (Galatians 3:2). The fruit of this Spirit is peace (Galatians 5:22), and those who bear the fruit of peace are the sons of God.
Our whole salvation, from beginning to end, is all of grace — therein lies our hope and joy and freedom. But our final salvation is not unconditional. We must be peacemakers. Therein lies the earnestness and great seriousness with which we must deal with these Beatitudes, and seek the grace of God in our lives.
Push For Peace
The promise of sonship in the second half of the Matthew 5:9 points us to Matthew 5:43–45 for our main insight. Both of these texts describe how we can show ourselves to be sons of God.
“You have heard that it was said, ‘You shall love your neighbor and hate your enemy.’ But I say to you, Love your enemies and pray for those who persecute you, so that you may be sons of your Father who is in heaven. For he makes his sun rise on the evil and on the good, and sends rain on the just and on the unjust.”
Notice verse 45: “So that you may be sons of your Father who is in heaven.” The thought is the same as in Matthew 5:9. There, we must be peacemakers to be called sons of God. Here, we must love our enemies and pray for those who persecute us if we would be sons of God.
“If our Father is a peacemaker, then his children will be peacemakers too.”
So probably Jesus thinks of peacemaking as all the acts of love by which we try to overcome the enmity between us and other people. And if we ask for specifics, he gives two examples:
First, pray for those who persecute you (Matthew 5:44). Pray what? The next chapter tells us. In Matthew 6:9–10 Jesus says, “Pray like this.” Pray that you and your enemy would hallow God’s name. Pray that God’s kingdom be acknowledged in your life and his life. Pray that you and he would do God’s will the way the angels do it in heaven. In other words, pray for conversion and sanctification. The basis of peace is purity. Pray for yours and pray for his, that there might be peace.
Then in Matthew 5:47, Jesus gives the other specific example of peacemaking-love in this text: “If you salute [greet] only your brethren, what more are you doing than others?” In other words, if there is a rupture in one of your relationships, or if there is someone who opposes you, don't nurse that grudge. Don't feed the animosity by ignoring and avoiding that person. That is the natural thing to do — just cross the street so that you don't have to greet them. But that is not the impulse of the Spirit of a peacemaking God, who sacrificed his Son to reconcile us to himself and to each other.
Peacemaking tries to build bridges to people — it does not want the animosity to remain. It wants reconciliation. It wants harmony. And so it tries to show what may be the only courtesy the enemy will tolerate, namely, a greeting. The peacemaker looks the enemy right in the eye and says, “Good morning, John.” And he says it with a longing for peace in his heart, not with a phony gloss of politeness to cover his anger.
Long for Peace
So we pray and we take whatever practical initiatives we can to make peace beginning with something as simple as a greeting. But we do not always succeed. And I want to make sure you don’t equate peacemaking with peace-achieving. A peacemaker longs for peace, and works for peace, and sacrifices for peace. But the attainment of peace may not come.
Romans 12:18 is very important at this point. There Paul says, “If possible, so far as it depends upon you, live peaceably with all.” That is the goal of a peacemaker: “If possible, so far as it depends on you . . . “ Don’t let the rupture in the relationship be your fault.
Peacemaking May Not Work
Yet, this raises a tough question: Is it your fault when the stand that you take is causing the division? If you have alienated someone and brought down their anger upon your head because you have done or said what is right, have you ceased to be a peacemaker?
Not necessarily. Paul said, “If possible . . . live at peace.” He thus admits that there will be times that standing for the truth will make it impossible. For example, he says in 1 Corinthians 11:18–19, “I hear that there are divisions among you. And I believe it in part, for there must be factions among you in order that those who are genuine among you may be recognized.” Now, Paul would not have said that if he meant for the genuine Christians to compromise the truth in order to prevent divisions at all cost. In fact, it was precisely because some of the Christians were genuine — genuine peacemakers — that some of the divisions existed (see also 1 Corinthians 7:15).
Jesus said in Matthew 10:34,
“Do not think that I have come to bring peace to the earth. I have not come to bring peace, but a sword. For I have come to set a man against his father, and a daughter against her mother, and a daughter-in-law against her mother-in-law. And a person’s enemies will be those of his own household.”
In other words, you must love peace and work for peace. You must pray for your enemies, and do good to them, and greet them, and long for the barriers between you to be overcome. But you must never abandon your allegiance to me and my word, no matter how much animosity it brings down on your head. You are not guilty; you are not in the wrong if your life of obedience and your message of love and truth elicit hostility from some and affirmation from others.
Aim for Purity over Peace
Perhaps it’s just this warning that Jesus wants to sound when the very next Beatitude says, “Blessed are those who are persecuted for righteousness’ sake.” In other words, righteousness must not be compromised in order to make peace with your persecutors. When Jesus pronounces a blessing on you for being persecuted for the sake of righteousness, he clearly subordinates the goal of peace to the goal of righteousness.
James 3:17 says, “The wisdom from above is first pure, then peaceable.” First pure, then peaceable — not the other way around. And that is the order we have in the Beatitudes also. First, “Blessed are the pure in heart,” then, “Blessed are the peacemakers.” Purity takes precedence over peace. Purity is the basis of biblical peace. Purity may not be compromised in order to make peace.
Jesus Cares About Your Soul
Now I want to close by dealing with one more question that a message like this would raise for some people today. Why, in view of the world situation, does this message on peacemaking confine itself to the personal dimensions of prayer and greetings and individual reconciliation? Aren’t these personal issues insignificant in comparison with the issues of nuclear war, military budgets, arms talks in Geneva, apartheid in South Africa, civil wars in Central America, religious oppression in Romania and Russia, and international terrorism?
“Purity is the basis of biblical peace.”
Before we answer that question, let’s ask another one. Was Jesus unaware that the iron hand of the Roman Empire rested on the tiny land of the Jews without their consent? Was he aware that Archelaus slaughtered three-thousand Jews at a Passover celebration? Was he aware that the Roman soldiers could conscript any Jew they chose to carry their baggage? Was he aware that Pilate had his soldiers bludgeon a crowd of Jews protesting his stealing from the temple treasury? Was he aware that Pilate massacred Jews on the temple ground and mixed their blood with their sacrifices they were offering?
When Jesus spoke of enemies, why did he confine himself to prayer and personal greetings and blessings and individual deeds of generosity and kindness? Why didn’t he talk about the issues of national humiliation, and Roman oppression, and political corruption, and the unbridled militarism of his day? Was he utterly out of touch with the big issues of his day?
Social Injustice Demands Personal Repentance
No, there is a better explanation for why he preaches the way he does. In Luke 13:1–5 some people confronted Jesus with one of Pilate’s atrocities. Here’s the way he responded:
There were some present at that very time who told him of the Galileans whose blood Pilate had mingled with their sacrifices. And he answered them, “Do you think that these Galileans were worse sinners than all the other Galileans, because they suffered in this way? No, I tell you; but unless you repent you will all likewise perish.”
He took a major social outrage of injustice and turned it into a demand for personal, individual repentance. “Unless you repent you will all likewise perish!” That’s what he always did. Why did he do this? Because for Jesus the eternal destiny of a human soul is a weightier matter, a bigger issue, than the temporal destiny of a nation.
If you come to Jesus with a question about the justice of taxes to Tiberias Caesar, he will turn it into a personal command aimed right at your own heart: “You give to Caesar the things that are Caesar’s and to God the things that are God’s” (Matthew 22:15–21).
If you come to Jesus with a complaint about the injustice of your brother who will not divide the inheritance with you, he will turn it into a warning to your own conscience, “Man, who made me a judge or arbitrator over you? . . . Take care, and be on your guard against all covetousness, for one’s life does not consist in the abundance of his possessions” (Luke 12:14–15).
Righteousness Is a Weighty Matter
Now let’s go back to the question: Why does a message on peacemaking from the Sermon on the Mount focus on the individual issues of prayer and greetings and personal reconciliation? Aren’t these personal issues insignificant in comparison with the issues of nuclear war, military budgets, arms talks in Geneva, apartheid in South Africa, civil wars in Central America, religious oppression in Romania and Russia, and international terrorism?
The answer is no, because the point of these personal issues in the Sermon on the Mount is to make crystal clear that every individual within the hearing of my voice must become a new creature if you are to have eternal life. You must have a new heart. Without a merciful, pure, peacemaking heart you cannot be called a son of God at the judgment day. And that is the truly weighty matter in the world today. Is the Son of Man confined in his views of the world, is he out of touch with the real issues of life because he regards the eternal salvation of your soul as a weightier matter than the temporal destiny of any nation on earth?
Blessed are you peacemakers who pray for your enemies and greet your opponents with love and sacrifice like your heavenly Father for the reconciliation of people to God and to each other, for you will be called sons of God and inherit eternal life in the kingdom of your Father.
