A Reader's Digest article told of a 67-year-old man named Bill who had donated over 100 pints of blood over the years. No doubt many people owe their lives to this man's kindness. How do you think this man's good deeds go over in heaven?

Here's what Bill thinks: "When that final whistle blows, and St. Peter asks, 'What did you do?' I'll just say, 'Well, I gave 100 pints of blood,'" [Bill] says with a laugh. "That ought to get me in."

Bill was probably joking. But if he was serious, if he truly believes that his good deeds will give him a ticket to heaven, then he has perfectly articulated the gospel of works. If Bill is counting on the giving of 100 pints of blood to get him to heaven—he is trusting in the wrong blood.
