Beloved, do not avenge yourselves, but rather give place to wrath; for it is written, "Vengeance is Mine, I will repay," says the Lord.
One of the hardest areas in which to trust God is in the matter of justice. When we perceive an injustice, we want to see the guilty party punished. We want justice to prevail, especially if we are the victim. We become impatient if we are not avenged quickly. Yet God warns us that vengeance is not our prerogative. We are to desire justice, but we are not to seek vengeance (Mic. 6:8). When someone offends us, our responsibility is to respond to the offense with forgiveness (Matt. 5:44). God takes the responsibility to see that justice is done. God loves people too much to allow sin to go unchecked.
Peter claimed that God is not slow about His promises to us, but He is patient and long-suffering before He brings about judgment (2 Pet. 3:9). Yet ultimately God has prepared for absolute justice. There will be no sin committed that He will leave unpunished. Either the punishment will fall on His Son or it will be charged against the sinner, but everyone will ultimately give an account for everything they have done (2 Cor. 5:10).
God is absolutely just, and only He can ensure that justice is fully carried out. If we are impatient and seek revenge, we presume that we are wiser than God, and we reveal a blatant lack of trust that God will do the right thing. Only by trusting God’s sovereign wisdom will we be free from our anger and preoccupation toward those who have committed evil. If we refuse to trust God’s justice, we become enslaved to bitterness and anger. We must guard our hearts and trust God to exercise His judgment against those who oppose Him.
