Jesus knew about the teachings of strict Pharisees and one time said they strained at a gnat but swallowed a camel. He also said they should remove the speck from their eyes before trying to remove the beam from the eyes of others. In other words they avoided slighter sins but practiced weightier ones such as their hatred for Jesus and His teachings.
Jesus not only condemned their teachings but during His Sermon on the Mount, gave a new law, or as He once said, He didn’t come to destroy the Law but to fulfill it. During that lengthy sermon, Jesus taught several moral principles: among them not to commit murder and adultery; then gave a new requirement for the law of Moses about revenge.
Jesus said people had heard an eye for an eye and a tooth for a tooth, but he says not to resist evil but whosoever slaps you on the right cheek to turn the other cheek. Then he says if anyone sues you and takes your coat to give your cloak also, and he continues by saying whosoever compels you to go one mile to go two miles.
I am not qualified to comment on these difficult requirements: I’m not sure if Jesus meant literally
to turn the other check or not to slap the assailant back. In the other two examples perhaps He is saying to do more than is required of us. But Jesus was teaching rather than seeking revenge, believers are to practice forgiveness. And Jesus not only taught these principles, He always set a worthy example for individuals by not fighting back while being humiliated and crucified. .
Father, give your children sufficient grace and strength not to seek revenge when harmed by another individual. This is possible only through the Holy Spirit Who indwells believer’s hearts. We ask for His divine help and pray in the Name of Jesus. Amen.
