But of Him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption: That, according as it is written, He that glorieth, let him glory in the Lord. – 1 Corinthians 1:30,31

My soul is free from slavery, but my poor trembling and much suffering body feels the chains of death. Weakened by pain, my body shall in all probability bow before the stroke of death’s sword. Unless the Lord soon come, it must be the portion of this frame to feed the worm and mingle with the dust: but, O my body, thou art redeemed, and thou shalt rise in power and incorruption; thou shalt yet adore the Lord without weariness, and without pain shalt thou serve Him day and night in His temple. Even thou, O my weary body; even thou shalt be made glorious like unto the Lord Himself: Thou shalt rise and live in the brightness of His presence.

You see then, brethren, our very existence as Christians, and all that we possess as Christians, we get from God by Jesus Christ; let all our glory then be unto Him. What insanity it is to boast in any but in our Lord Jesus! How foolish are they that are proud of the beauty of their flesh-worms’ meat at the best! How foolish are they who are proud of their wisdom! The wisdom of which a man is proud, is but folly in a thin disguise. How foolish are they that are vain of their wealth! He must be a poor man who can think much of gold. He must be a beggar indeed who counts a piece of dirt a treasure. They that know Christ, always value these things at their right estimate, and that is low indeed. If any glory-and I suppose it is natural to us to glory, there is a boasting bump on all our heads-let us glory in the Lord; and here is a wide field and ample sea-room. Now, put out every stitch of canvas, run up the topgallants, seek as stiff a breeze as you will, there is no fear of running on a lee shore here, or striking a rock, or drifting on a quicksand! O men, O angels, O cherubim, O seraphim, boast in Jesus Christ! Wisdom, righteousness, sanctification, and redemption is He, therefore ye may boast and boast, and boast again! ~ C.H. Spurgeon
