The Bible makes it clear that false accusations are evil and should have no place in the life of a believer. Some people make false accusations as a way to seek revenge. They want to harm the person they are falsely accusing. Some do it as an attempt to gain or maintain power. The Bible, in both the Old and New Testaments, strongly condemns false accusations. We are called to “put away all malice and all deceit and hypocrisy and envy and all slander” (1 Peter 2:1). Instead, we are called to speak the truth in love (Ephesians 4:15, 25). Clearly falsehood of any kind is contrary to God's character, and thus it has no place in the life of a believer.
Throughout our lives, we will have people falsely accuse us, but instead of acting in any sort of violent retaliation, we can rest in the fact that God knows the truth. Peter instructs us to behave in such an upright way that it puts our accusers to shame: "Having a good conscience, so that, when you are slandered, those who revile your good behavior in Christ may be put to shame" (1 Peter 3:16). Jesus actually said that we are blessed when this happens to us for His sake: "Blessed are you when others revile you and persecute you and utter all kinds of evil against you falsely on my account. Rejoice and be glad, for your reward is great in heaven, for so they persecuted the prophets who were before you" (Matthew 5:11–12). It is not up to us to avenge ourselves (Romans 12:19). We should seek wisdom from the Word so that in all circumstances we may honor God (Psalm 119:69–70).
Stay strong; God sees and knows the truth. We can be encouraged by David’s prayer in Psalm 43: “Vindicate me, O God, and defend my cause against an ungodly people, from the deceitful and unjust man deliver me! … Why are you cast down, O my soul, and why are you in turmoil within me? Hope in God; for I shall again praise him, my salvation and my God (Psalm 43:1, 5; also see Psalm 27:2; Romans 8; 12:19; 1 Timothy 5:24–25).
