Colossians 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.”
When Jesus Christ Sacrificed Himself on the Cross, He reconciled “all things unto himself”. The “all things” refers to “all” the “Elect according to the foreknowledge of God the Father” (I Peter 1:2), which included those “things in earth, or things in heaven”; that is, those who are already deceased, those who were alive at that time, and those who were yet to be born. It also included both the Jews and the Gentiles (Colossians 1:21-22). The Gentiles were summarily rejected by the Jews, but the Lord lovingly included His Children among the Gentiles in the “all things”. In this context to “reconcile” is to have been made to be eternally at “peace” with God the Father. To obtain this blessed and holy “peace”, the judicial price for sin had to be paid, and the penal price was the “blood of his [Jesus Christ] cross”. And at the very instant that He declared “It is finished” (John 19:30), He fully and finally and forever reconciled “all” His Children to Himself; that is, now “we are sanctified through the offering of the body of Jesus Christ once for all” (Hebrews 10:10).
