Here are excerpts from a blogpost over two years ago…
And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence. 19 For it pleased the Father that in him should all fullness dwell; 20 And, having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven (Col 1:18-20 KJV).
Jesus is the Creator of the Church, and He was the first to be raised from the dead as it regards the Resurrection. The Cross of Christ addressed the fall of man, satisfying the just demands of the broken Law, that Believers might be reconciled unto God.
And you, that were sometime alienated and enemies in your mind by wicked works, yet now hath he reconciled 22 In the body of his flesh through death, to present you holy and unblameable and unreproveable in his sight: 23 If ye continue in the faith grounded and settled, and be not moved away from the hope of the gospel, which ye have heard, and which was preached to every creature which is under heaven; whereof I Paul am made a minister (Col 1:21-23 KJV).
Paul encourages the Believers of Colosse to continue in the Faith as delivered to them by the Apostles.
Who now rejoice in my sufferings for you, and fill up that which is behind of the afflictions of Christ in my flesh for his body’s sake, which is the church: 25 Whereof I am made a minister, according to the dispensation of God which is given to me for you, to fulfil the word of God; 26 Even the mystery which hath been hid from ages and from generations, but now is made manifest to his saints (Col 1:24-26 KJV).
Paul did not want to become sidetracked on some minor issue that did not emphasize the centrality of the Gospel, which is Christ and Him Crucified. The Mystery of the Gospel of Salvation by Grace through Faith in Jesus Christ is made manifest in the Believers, not in the world.
To whom God would make known what is the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory: 28 Whom we preach, warning every man, and teaching every man in all wisdom; that we may present every man perfect in Christ Jesus: 29 Whereunto I also labour, striving according to his working, which works in me mightily (Col 1:27-29 KJV).
The full realization of Christ in the Believer, the Hope of Glory, will materialize at the coming Resurrection.
