When people come to me and say, ‘What does the Bible teach I should do when I’m persecuted?’ I say, ‘It’s simple. You want to not go get them and hate them. The Bible says reverse that. You have to go get them and love them.’ What do people say? ‘Impossible. That’s ridiculous.’ Of course, that’s what the Bible says you’re supposed to do. That’s what turn the other cheek means.
Turn the other cheek does not mean you let people walk all over you. Absolutely not. Paul didn’t; he appealed to Caesar. Jesus didn’t; he protested when he was struck. ‘Hey, this is illegal,’ he said. The Bible always says you uphold justice for the sake of justice, but you let God be the judge. You give over the ultimate judgment of that person’s character to God and you go after justice without any vengefulness in your heart. You forgive.
