In Colossians 3:11, Paul says (echoing v. 4 — “Christ, who is our life…”), “Christ is all, and in all.” That is, Christ is all-sufficient. He is everything a believer needs and He is everything to that believer. And He is in all believers equally — no one gets an extra dose of Jesus. His sufficiency and power is available to all believers equally.
Christ is all. He is all a believer needs to be sustained and He is all a believer should desire. He is supreme.
John Newton affirms that truth in the final two stanzas of his hymn, “What Think You of Christ?”
Some style [i.e., call] him the pearl of great price,
And say he’s the fountain of joys;
Yet feed upon folly and vice,
And cleave to the world and its toys:
Like Judas, the Savior they kiss,
And, while they salute him, betray;
Ah! what will profession like this
Avail in his terrible day?
If asked what of JESUS I think?
Though still my best thoughts are but poor;
I say, he’s my meat and my drink,
My life, and my strength, and my store,
My Shepherd, my Husband, my Friend,
My Savior from sin and from thrall [i.e., bondage];
My hope from beginning to end,
My Portion, my LORD, and my All.
