Matthew presents Christ from the perspective of His kingdom. Mark presents Him from the perspective of His servanthood. Luke shows Him from the perspective of His humanity. John shows Christ from the perspective of His deity.
Each writer, inspired by the Holy Spirit, showed a different aspect of the Person Christ. Each is part of the whole. Each equally important. Taken together, we have the full picture of the Son of God.
Christ, the perfect Son of God is also the son of Man. Altogether beautiful, perfect and complete, He is Lord of All, in all ways, at all times. Serve Him.
