2:1-7 The soul prospers when we have clear knowledge of the truth as it is in Jesus. When we not only believe with the heart, but are ready, when called, to make confession with the mouth. Knowledge and faith make a soul rich. The stronger our faith, and the warmer our love, the more will our comfort be. The treasures of wisdom are hid, not from us, but for us, in Christ. These were hid from proud unbelievers, but displayed in the person and redemption of Christ. See the danger of enticing words; how many are ruined by the false disguises and fair appearances of evil principles and wicked practices! Be aware and afraid of those who would entice to any evil; for they aim to spoil you. All Christians have, in profession at least, received Jesus Christ the Lord, consented to him, and taken him for theirs. We cannot be built up in Christ, or grow in him, unless we are first rooted in him, or founded upon him. Being established in the faith, we must abound therein, and improve in it more and more. God justly withdraws this benefit from those who do not receive it with thanksgiving; and gratitude for his mercies is justly required by God.
6. "As therefore ye received (once for all; the aorist tense; from Epaphras) Jesus the Christ as your Lord (compare 1Co 12:3; 2Co 4:5; Php 3:8), so walk in Him." He says not merely, "Ye received" the doctrine of Christ, but "Jesus" Himself; this is the essence of faith (Joh 14:21, 23; Ga 1:16). Ye have received once for all the Spirit of life in Christ; carry into practice that life in your walk (Ga 5:25). This is the main scope of the Epistle.
