'If I had to summarize New Testamenty ethics in one sentence, here's how I would put it: be who you are. That may sound strange, almost heretical, given our culture's emphasis on being true to yourself. But like so many of the worst errors in the world, this one represents a truth powerfully perverted. When people say, "Relax, you were born that way." or "Quit trying to be something you're not and just be the real you," they are stumbling upon something very biblical. God does want you to be the real you. He does want you to be true to yourself. But the "you" he's talking about is the "you" that you are by grace, not by nature. You may want to read through that last sentence again because the difference between living in sin and living in righteousness depends on getting that sentence right. God doesn't say, "Relax, you were born this way." But he does say, "Good news, you were reborn another way."'
