For it pleased the Father that in Him should all fullness dwell… – Colossians 1:19

“It pleased the Father that in Him should all fullness dwell.” Two mighty words: “fullness”- a substantial, comprehensive, expressive word in itself, and “all”- a great little word including everything. When combined in the expression, “all fullness,” we have before us a superlative wealth of meaning.

Blessed be God for those two words. Our hearts rejoice to think that there is such a thing in the universe as “all fullness,” for in the most of mortal pursuits utter barrenness is found. “Vanity of vanities, all is vanity.” Blessed be the Lord forever that He has provided a fullness for us, for in us by nature there is all emptiness and utter vanity. “In me, that is, in my flesh, there dwelleth no good thing.” In us there is a lack of all merit, an absence of all power to procure any, and even an absence of will to procure it if we could. In these respects, human nature is a desert, empty, and void, and waste, inhabited only by the dragon of sin, and the bittern of sorrow. Sinner, saint, to you both alike these words, “all fullness,” sound like a holy hymn. The accents are sweet as those of the angel-messenger when he sang, “Behold, I bring you glad tidings of great joy.” Are they not stray notes from celestial sonnets? “All fullness.” You, sinner, are all emptiness and death, you, saint, would be so if it were not for the “all fullness” of Christ of which you have received; therefore, both to saint and sinner the words are full of hope. There is joy in these words to every soul conscious of its sad estate and humbled before God. ~ C.H. Spurgeon
