I would also strongly recommend his book “God is the Gospel.” If I were to sum up the premise of the book it would be; The gospel is like a a treasure hidden in a field that a man found and hid. In his joy he went away and sold everything he had and bought that field. God is that treasure. The Gospel is that we get God. Our sin is forgiven, Jesus completes his work on the Cross, and the Holy Spirit infuses us; SO THAT we get God. Beautiful.
