Ps. 37:12 begins to shed more light upon the situation about which David is writing. The difficulty in navigating this world is not just that the wicked do evil, but that the wicked develops evil plots against God’s people out of hatred for God’s people. That is very obvious to the Lord, who scoffs at their plans (v.13), not because he will always stop them from carrying out their schemes, but because he knows what’s in store for the wicked who do not repent. Their day of reckoning is coming and it’s a day of justice being meted out with absolute precision.
This is why we don’t need to spend too much time proving that people do evil and that we are wronged by that evil. We would do better spending that time committing our ways to the Lord and waiting on him (vv.5,7).
