Christ is all, and in all. – Colossians 3:11

There are many things in this world that are good, but there is nothing that is good for everything. Some plants may be a good medicine, but not a good cordial; the plant of renown (Ez.34:29) is good in every way. Good clothing is not able to stay your hunger, but Christ the bread of heaven is also the Father’s best robe. You cannot expect any finite thing to be good for all things, but Christ is infinite goodness. This tree of life bears all manner of fruits, and the leaves are for the healing of the nations. He is strength and beauty, safety and sanctity, peace and plenty healing and help, comfort and conquest, life here, and life for ever. Glory be to the Lord Jesus Christ! What can He be less than God, if He be all? “All.” Is it not a synonym for God? We say there cannot be two Gods, because the one God is everywhere, and fills all space; and who then can He be who is called “all in all,” but “very God of very God?” Worship Him, my brethren, with all your hearts; rejoice in Him and bless Him from day to day. Let not the world think you poor who are so rich in Him. Never suffer men to think you unhappy, who have perfect happiness in the ever-blessed Immanuel.

Oh, the blessedness of the man who can say, “Christ is mine.” On the other hand, see the wretchedness of the man who has not the Savior: for if Christ is all, you who believe not on Him are devoid of all, in being destitute of Christ. But you say, “I try my best, I attend public worship, I do a great deal that is good;” you have nothing if you have not Christ. Do not flatter yourself that you are getting on and adding goods to goods in spiritual things; if you have not a Savior you are naked and poor and miserable; you are without all if you are without Christ, who is all. The Christian, then, is rich, but everyone who is destitute of Christ is poor to the extreme of poverty. ~ C.H. Spurgeon
