For in Him dwelleth all the fullness of the Godhead bodily and you are complete in Him, who is the head of all principality and power. – Colossians 2:9,10
When John saw the Son of Man in Patmos, the marks of Deity were on Him. “His head and His hairs were white like wool, as white as snow”-here was His eternity; “His eyes were as a flame of fire”-here was His omniscience; “Out of His mouth went a sharp two-edged sword”-here was the omnipotence of His word; “And His countenance was as the sun that shineth in his strength”-here was His unapproachable and infinite glory. He is the Alpha and Omega, the beginning and the end, the first and the last. Hence nothing is too hard for Him. Power, wisdom, truth, immutability, and all the attributes of God are in Him, and constitute a fullness inconceivable and inexhaustible.
Fullness dwells in our Lord not only intrinsically from His nature, but as the result of His mediatorial world. He achieved by suffering as well as possessed by nature a wondrous fullness. He carried on His shoulders the load of our sin; He expiated by His death our guilt, and now He has merit with the Father, infinite, inconceivable, a fullness of desert. The Father has stored up in Christ Jesus, as in a reservoir, for the use of all His people, His eternal love and His unbounded grace, that it may come to us through Christ Jesus, and that we may glorify Him. All power is put into His hands, and life, and light, and grace, are to the full at His disposal. “He shutteth and no man openeth, He openeth and no man shutteth.” He has received gifts for men, yea, for the righteous also. Not only as the Mighty God, the Everlasting Father, is He the possessor of heaven and earth, and therefore filled with all fullness, but seeing that, as the Mediator, He has finished our redemption, “He is made of God unto us wisdom, and righteousness, and sanctification, and redemption.” Glory be to His name for this double fullness. ~ C.H. Spurgeon
