Andy listens to Chapter 4 of Francis Chan's book, Crazy Love.
Chan teaches that a crazy love from God demands a crazy response from us. But... too many people who claim to be Christian are responding in lukewarm ways.
In Chapter 4 of Crazy Love, Chan details the profile of a lukewarm person. The lukewarm person is not the good soil of Jesus' "Parable of the Sower and Soils." The lukewarm person is not a lukewarm Christian, since lukewarm Christian is an oxymoron.
The kicker though is that we all have elements of lukewarmness in our lives, and even Chan admits this, so wouldn't that mean none of us our saved? How would we know if we have too much lukewarmness in our lives to be counted among God's people?
The biggest problem is that Chan is pointing us towards ourselves for assurance of our justification and not to Christ and his saving work. He is saying that a fulfillment of the Law on our part is how we can know if we are really saved or not.
Crazy Love is an immensely popular book and Andy knows someone who doubted his salvation after reading Crazy Love. Whenever we are pointed to look at ourselves and not to Christ, we will inevitably doubt our salvation if we are are not deceiving ourselves concerning our sinfulness.
