“An eye for an eye” seems fair (and was stated so in Leviticus for legal guidance). But Jesus’ teaching was directed at personal hearts and attitudes, not jurisprudence. Based on that He said this:
“You have heard that it was said, ‘An eye for an eye and a tooth for a tooth.’ But I tell you not to resist an evil person. But whoever slaps you on the cheek, turn the other to him also.” – Matthew 5:38-39 NKJV
Those words are simply not easy to receive. The natural person inside wants to place all kinds of conditions and prerequisites on them. But the truth is, Jesus said what He meant. At the personal level, a follower of Christ must look beyond the moment and find strength in the Lord to be a channel of grace. It doesn’t mean tolerance for abuse or such things, there are appropriate measures for that, but it does mean an internal “giving up” of the personal “right to vengeance”. It takes a strong resolve to stand firm and display internal strength when it may look like cowardice. But in the end, who’s the stronger? The word “meek” in the scripture doesn’t mean weak, it means “strength under control”. It’s the word picture of a powerful horse that’s usable. Will you choose to be strong in Him today?
