TC, it is a mystery. Me and my brother were talking about this the other day, and we came to the conclusion that Christians are sanctified by how much exposure they have to the truth, i.e. preaching and teaching. I was looking at the people in my church and people who seem to be spiritually stagnant. Then I seen my friend Derek and my brother Matt, both who have been saved for about a year and are growing leaps and bounds.
Matt and Derek both listen to great teachers and preachers, while the majority of other people at my church only listen to our Pastors sermons. Matt has listened to MacArthur, Paul Washer, Sproul, and others, and Derek has listened to Ray Comfort and has been devouring Spurgeon's sermons. As they hear the Word preached and taught, it is amazing to see how it molds them.
