I just got finished reading What's so amazing about grace? by Philip Yancey. It's a great read (props to my boy Bailey for recommending it). The book really does a great job of showing how free grace really is. If you're like me, you've run into times in your life where you feel like the disciplines of the Christian life are THE goal, and somehow serve to make God like you more. Yancey does a great job of breaking through all the legalistic practices, as well as all the wounds from legalism, and expounding on the idea of God's accepting us wholly on the work of Christ.
He speaks mainly at his days at a Bible college that was beyond legalistic. He says:
"When I attended a Bible college, I observed people who followed the rules and missed God, and people who broke the rules and missed God. What burdens me, though, is that group of people who still believe that they missed God BECAUSE they broke the rules. They never heard the melody of the gospel of grace."
So, do yourself a favor and check out the book. It's a good one.
