"Truthful words stand the test of time, but lies are soon exposed." Proverbs 12:19 NLT
We often get upset when we find out that someone has lied about us. It is merely a trick of the enemy to get us focused on the pain of betrayal. He doesn't want us to stay in the will of God. Satan wants us distracted from the prize, so we won't press toward it. He wants us to waste time lashing out about it and trying to fix it.
God wants us to forget about those things behind us. How can we see the road ahead of us while looking backwards? We need to let things go. We must forgive the people who hurt us with their lies. We must disassociate ourselves from messy people and love them from a distance. Some lies get told because of our associations, but even cutting those bad relationships loose, lies will still be told.
Satan is the father of lies. Recognize the enemy for who he is, and stop trying to fight battles God has already won. You don't need to defend yourself against a lie. Lies die...if YOU let them. Let people make up stories about you all they want, but you continue to do what is right in the sight of God. The lies will soon be exposed! As for the people who want to believe lies (gossip), pray for them and keep them out of your business! People don't need to know everything God has revealed to you, and they certainly don't need to know everything going on with you.
The most important relationship you have is that between you and Jesus Christ. Cast all your cares on Him because He cares for you. Leave liars be, and let lies fade into vapors without you stirring them up, giving them power over you. God's Word is the truth, and it will stand forever! Rebut every lie told against you with the Word of God, and be encouraged in the Lord!
