The death of Christ does not turn away the wrath of God from all people. In order to benefit from the work that God has done outside of us, we must now experience the work that he does within us by the Holy Spirit. What is this work and how is it related to the gift of justification?
If we are unmerciful, unforgiving people, if we hold grudges or cherish resentments or plan revenge, then what we are saying in effect to God is, "This is the way I prefer life to be." And so he will give us what we have preferred at the day of judgment; no mercy, no forgiveness, but only vengeance. If Christ has not changed us (and I don't mean perfection, but only significant change), then probably we have never known him.
The glory of the preeminence Christ is the ultimate goal of predestination.
The doctrines of sovereign grace are not overthrown by problems in Scripture. They stand firm and are the precious foundation of our deepest hopes.
It is faith alone which justifies, but that the faith which justifies never stays alone. It is living and active and bears fruit in obedience.
