What is the purpose of preaching? Is it to increase knowledge or provoke akSHUN? Randy Nabors thinks the latter:
We don’t need more didactic moments that simply tickle the minds of those who thirst for more information; we need the forming of the heart though great sermons powerfully delivered. People need truth that shapes hearts into the obedience that comes through faith so people can be doers of the Word and not just hearers of it.
But what if the average Christian believer is someone who is prone to think either that sin, temptation, the devil, and the flesh have overwhelmed him the previous week? What sort of sermon does that person need? A call to obedience? Maybe. But can such a call make sense to someone who knows how sinful and weak he is? Might the person in the pew need to hear about God’s work in sanctification even if it is a tad didactic?
Or what about the average believer who lives life like a pilgrim, someone in exile, hardly in command of his affairs, but weak, frail, and in need of a reminder that God has saved him and controls all things?
In other words, Nabors seems to think of Christians as people who are in control of life and need simply to be hectored into living Christian lives. He doesn’t seem to allow that Christians come to church thinking that they believe, but are tempted to unbelief precisely when they take life and its duties into their own hands.
