If I believe all the right things, then why does my growth in holiness seem so tedious and slow? Why is my theology not changing my life? Or at least, not changing me as fast as I thought it would? Anyone who regularly plunges into the riches of Scripture and of the Reformed tradition will eventually face this very sobering and probing question. The topic was taken up by Pastor John and by the late R.C. Sproul at a Ligonier National Conference back in 2011. The conversation was on stage. There the dialogue turned toward how the mind and heart relate to the discovery of biblical truth. We jump into the conversation, beginning with Pastor John.
