Colossians 2:3

Are hid. Or, “are stored away.” In Christ, in His office and function, in His person and ministry, in the fact that He is both Son of God and Son of man, are embedded the details of the mystery of God. He is the source as He is the treasure house of the blessings of God. Paul desired to lift the minds of the Colossian Christians above and beyond mere human ideas to God’s Son and the eternal virtues and verities revealed in Him. In Christ may be discovered all that God purposes to reveal in blessing for humanity. Why, then, should the Colossians give ear to human speculations (see on v. 4)?

All the treasures. Jesus is the mine from which all true riches come. To those who receive Him, He gives truth in its fullness. Other teachers have given partial and obscure glimmerings of knowledge, but in Christ, the living Word, resides the essential knowledge. See COL 104—114.

Wisdom and knowledge. Christ is the treasure house of divine wisdom and knowledge (see 1 Corinthians 1:22, 24; Ephesians 3:9-11). Those who receive Jesus have come to the source of all they need for this life and for the hereafter.
