Jesus said that our union with Him is to be the source of everything in our lives and ministries. We are to live by His indwelling life in the same way that He lived and ministered out of the indwelling life of His Father.
Jesus lived in continuous fellowship with His Father, and through that fellowship He drew from, and lived by, His Father's life. Thus, Jesus' leadership came from His union with His Father. And, just as Jesus' continuous inward fellowship with His Father was the source of everything in His life and ministry, so our inward fellowship with God is to be the source of everything in our lives and ministries!
