And have put on the new man, which is renewed in knowledge after the image of Him that created him: …Christ is all, and in all. – Colossians 3:10,11

Paul does not say that Christ is all in all to all men, but he tells us that there is a new creation, in which the man is “renewed in knowledge after the image of Him that created him,” where all national and ceremonial distinctions cease, and Christ is all and in all. It is not to every man that Christ is all and in all. Alas! there are many in this world to whom Christ is nothing; He scarcely enters into their thoughts. Some of the baser sort only use His name to curse by; and as to many others, if they have a religion, it is a proud presumption which excludes a Savior. The creed of the self-righteous has no room in it for the sinner’s Savior; the justifier of the ungodly is nothing to them. The worldly, the frivolous, the unchaste, the licentious, these do not permit themselves to think of the Holy Redeemer. Perchance some such are now present, and though they will hear about Him and of nothing else but Him, they will say, “what a weariness it is,” and be glad when the discourse is ended. Jesus is a root out of a dry ground to multitudes, to them He hath no form nor comeliness, and in Him they see no beauty that they should desire Him. Ah, what will they do when He is revealed in the glory of His power? They thought it nothing to them as they passed by His cross, but they will not be able to despise Him as they stand convicted before His throne. O ye who make Jesus nothing, kiss the Son lest He be angry, and ye perish from the way, when His wrath is kindled but a little. Without Christ, you are to-day without peace, and will be for ever without hope! Nothing remains for Christless souls at the last, but a fearful looking for of judgment and of fiery indignation. I could well pause here, and say, let us pray for those who are unbelievers, and so are living without a Savior, that they may not remain any longer in this state of condemnation. ~ C.H. Spurgeon
