Actually it wasn't helpful. Not speaking to you, but it does sound like something that could be written by those who would pat their flesh on the back for writing something approved by those just as 'indoctrinated' as themselves, though.
COL 1:15 He is the image of the invisible God, the first-born of all creation;
16 for IN HIM/'CHRIST' all things were created, in heaven and on earth, visible and invisible, whether thrones or dominions or principalities or authorities -- all things were created through him and for him.
COL 1:20 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.
So, according to scripture: IN HIM/in Christ, all things were created by and for Him. And, 'by the cross' all things HAVE BEEN reconciled to Christ who was hidden IN GOD.
EPH 3:9 And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:
Those still "hid in God" from the ages before the cross to the "ages after the cross" WILL be reconciled to God, even as God has ALREADY reconciled Himself to them, by the cross. God doesn't have a sin problem with anyone ETERNALLY. Jesus paid that ETERNAL price for all. It is simply a question as to when 'YOUR TURN, TO TURN' will come. Some bow the knee here, most don't. But this is a fact; "EVERY knee SHALL BOW and every tongue SHALL CONFESS to the glory of God." and not to His shame for letting Satan win almost ALL. How stupid is omniscience, if such a thing ever happened?
JOB 14:14 If a man die, shall he live again? All the days of my service I would wait, till my release should come. 15 Thou wouldest call, and I would answer thee; thou wouldest long for the work of thy hands.
If HE fails to save "IN HIM ALL" that was created for HIM, then he was never Saviour of all, at all. Therein is the lie of the church whose theological roots are claimed to go all the way back to Peter is producing the same fruit in all her descendants. Mine roots go back farther, to CHRIST.
The 'Mystery hid 'in Christ' 'in God' is still hid to most.
