Depth isn’t limited exclusively to pure Bible knowledge.  It’s about truly grappling with and striving to process information, decisions, and choices in a way that honors God.  Depth means learning about God as you simultaneously learn more about yourself and this world. 

John Calvin once said, "Nearly all the wisdom we process, that is to say, true and sound wisdom consists in two parts: the knowledge of God and of ourselves. But, while joined together by many bonds, which one precedes and brings forth the other is not easy to discern."
