Jesus, as the Firstborn of Creation, (15) did what Adam could not do. He lived by God as His life in all things. Adam could not properly multiply and fill the earth with many brothers and sisters and neither could he have proper dominion over the earth. He did not do it , he instead brought sin and death.
Jesus, however, demonstrated real dominion over the earth and Heaven, both visible and invisible powers. Political and religious powers, Satanic and demonic powers. (16)
Jesus also multiplied His life and became the firstborn of many brothers and sisters. We have received his life and have been brought into his identical relationship with the father. Praise the Lord! (Romans 8:29).
He is also the first born from the dead end (verse 18). This is how he did it. He brought that life that pleased the father in all things to the cross, was resurrected, ascended, as a man presented his accomplishment to the father, and thus has dispensed this life into the Holy Spirit, who now lives in us Enabling us to be the many brothers and sisters. This, we shall see, is how he is gaining first place in all things in the universe through the church! Amen!
