“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 your right cheek, turn the other to him also. If anyone wants to sue you and take away your tunic, let him have your cloak also. And whoever compels you to go one mile, go with him two. Give to him who asks you, and from him who wants to borrow from you do not turn away.
From Jesus’ Sermon on the Mount, Matthew 5:38-42.
Jesus is teaching us not to retaliate. That is what “turn the other cheek” means. He is also telling us to be generous towards those who seek our help — going the second mile and “let him have your cloak also”. As His followers, Jesus is calling upon us to be radically different from the world.
