Luke 17:2; It were better for him that a milestone were hanged about his neck, and be cast into the sea, than that he should offend of these little ones.
God takes the persecution of His children personally. In Acts 9:4; when Jesus appeared to Saul on the road to Damascus and spoke to him about his persecution of the saints, Jesus said,"Saul, Saul, why persecutest thou Me?" Saul was not directly persecuting Jesus, but he was persecuting His saints. Yet Jesus said, "Why are you persecuting Me?" Judgment against those who persecute God’s children will not always come in time to prevent their harm, but as this warning makes very clear, God will avenge His own, (Rom. 12:19;)
Letting God be the one to defend us is a matter of faith. If there is no God who will hold people accountable for their actions, then turning the other cheek could be the worst thing we could do. But since there is a God who promises that vengeance is His and He will repay, then taking matters into our own hands shows a lack of faith in Him and His Word.
Jesus did not come to condemn the world, and He is not holding people’s sin against them. We should do the same. If someone has taken advantage of you, betrayed you,or slandered you, remember what Jesus told Saul."Whatever you say and do to My followers you say and do to Me!"
Your Heavenly Father knows all and He will defend you!
God Bless your Heart!
