" All the fullness of God is in Jesus (Colossians 2:9). All the treasures of wisdom and knowledge are in Jesus (Colossians 2:3). Beyond what the Old Testament told us, whatever we need to know about God and how he relates to our lives we learn from what we hear and see in God’s final, decisive Word, Jesus Christ. "
