Colossians 1:19-23 Reconciled In Christ.
When it says that “it pleased the Father that in Him all the fullness should dwell,” it is referring to the incarnate Son, because the pre-incarnate Son has always had the fullness (v. 19). The point is that the person of Jesus Christ was fully God and fully man, two distinct natures in one person. These two natures are not mixed, nor is either diminished in the union. This is the orthodox understanding of the person of Jesus Christ, and the only position which takes into account all that the scriptures teach concerning Him. This is also the only way He could offer up Himself as a sinless spotless sacrifice for sin. The further proof that it is the incarnation which Paul has in view is borne out by what he states next-that “by Him to reconcile all things to Himself, by Him, whether things on earth or things in heaven, having made peace through the blood of His cross” (v. 20). This is the finished work of the incarnate Son in His once for all sacrifice for sins (v. 14).
So the Son is the inheritor of all things, both because the Father created all things through Him, whether things in heaven or on earth, including principalities and powers, but also because through Him alone redemption has come (vv. 16, 20). Paul has already made note of the fact that we were once held captive by the power of darkness, and here Paul also states that this state showed itself “by wicked works,” works which stemmed from the reality that Paul’s readers and us with them, like the world, were alienated from God by our being enemies in our minds against Him (v. 21). It is through Christ’s offering up of Himself unto death, that His people have been reconciled to the Father, that we might then be presented to Him “blameless, and above reproach” (v. 22 Cf. II Cor. 5:18-19; Eph. 1:10; 2:1; 5:27). Perseverance, keeping the faith and bearing fruit to the end, is in fact a sign of this reconciliation (v. 23 Cf. 1:6).
