Christ is the truth in the fullest sense. The Holy Ghost is also called "truth" (1 John 6), as being the inward power in him that believes for laying hold of the revelation of God and realizing it. Jesus is the truth. The truth is the expression of what God is and what man is. He who is the truth objectively must be both God and man to make known the truth about them. He is not only God, but the special One who makes known God, and, being man, He could make known man; yea, being both, He could make known everything. Thus we never know what life is fully save in Christ, and we never know what death is save in Christ. Again, who ever knows the meaning of judgment aright save in Christ? Who can estimate what the wrath of God is save in Christ? Who can tell what communion with God is save in Christ? It is Christ who shows us what the world is; it is Christ who shows us what heaven is and by contrast what hell must be. Some ancient philosophers said, though falsely, that man is the measure of all things. It is exactly true of Christ, the God-man.
