It is important that we know the nature of the evil in our hearts.
Do you think the essence of your evil is disobeying commandments? That’s a good start. But it’s not the essence of our evil. Commands simply name the evil and its fruits, and tell us not to do them.
The essence of our evil is that we prefer anything to God (Romans 1:23; 2:23). Commands do not create the possibility of evil. Commands name it.
Long before we are told not to covet, we covet. Disobeying the command, “Thou shalt not covet,” is not equivalent to the evil of coveting. The evil of coveting is there first, and then is compounded by the transgression of the commandment not to covet.
Paul said, “I would not have known what it is to covet if the law had not said, ‘You shall not covet’” (Romans 7:7). That is, I wouldn’t have known the seriousness of my evil if God had not named it in the law.
But lawbreaking is not the essence of my evil. Desiring anything above God is the essence of my evil, before any commands name it.
One reason this is important to know is that it will affect the way you pursue change. If you think the essence of your evil is commandment-breaking, your focus for change will be commandment-keeping.
That is doomed to fail for two reasons. If we get good at it, we think we have changed, but the essence of our evil remains. If we can’t get good at it, we despair and quit trying.
But if we know that the essence of our evil is not commandment-breaking, but preferring anything to God, then our focus for change will be a change of heart. That is hopeful, because God promised, “I will remove the heart of stone from their flesh and give them a heart of flesh” (Ezekiel 11:19).
This is the new covenant that Jesus purchased with his blood (Luke 22:20). We receive it by faith.
