Sound doctrine is so important. But we can never settle for merely knowing doctrine. God has given us his Holy Spirit, and he invites us to ask to be continually filled with his Spirit afresh so that doctrine becomes the living story of God’s great love for us. So that it melts our hearts. So that this truth sets us on fire with love for the Savior who loved us first. The glorious truth of God’s love for us in the giving of his Son isn’t something we can grasp through mere knowledge or bigger books. We need the power of God’s Holy Spirit to give us “strength to comprehend” how big and wide an ddeep God’s love for us is (Ephesians 18-19).
