Grace sounds too good to be true until you realize it cost Somebody everything.

Grace is free to you, and that is exactly what makes it hard to believe. Anything handed over with no conditions sounds like a trick, until you look at what it cost on the other end. It was not cheap, it was paid for, and the bill did not come to you.

When you catch yourself trying to earn what you have already been given, stop and say thank you instead. Let the price of it keep you honest about how you treat other people. Received that way, it tends to leave your hands rather than sit in them.
