From Reformation Theology:
Most Christians do not think enough, or study enough in order to pursue God with their minds as well as their hearts, but as Dr. John Piper reminds us, there is a ditch on the other side of the road – an intellectualism that pursues the study of God without relationship with God. In the short video below, he encourages Christians to value theology as a means for knowing God, without making theology God.
Already Not Yet 
This is simply an excellent warning and gentle rebuked we Reformed people need to hear and take to heart. God is to be worshiped by faith in Jesus, but in spirit and in truth. Good post.
