He is the image of the invisible God, the firstborn of all creation.Colossians 1:15(NASB)
The Lord Jesus in His humanity is the visible revelation of the invisible God. This is a great mystery but it is a truth that has been given to us from the Creator of the universe. The only way for sinful humanity to be reconciled to a holy God is through the shed blood of the eternal Son of God, Who died to pay the price for our sins so that we might be covered with His righteousness and reconciled back to the Father.
The only way to discover the invisible God is through person of the Lord Jesus Christ, Who is the visible image of the invisible God - God manifest in the flesh. The only way know our Creator intimately is through His only begotten Son, the Lord Jesus Christ, Who is the firstborn over all creation.
The word firstborn does not refer to time for the uncreated Son is from everlasting to everlasting. The word firstborn refers to His preeminent position in God's creation - His superior standing; His predominant place; His supreme status. Christ is the firstborn over all creation because as the eternal Son of God He was born into our race as the perfect Son of Man. The incarnate Word was made flesh and dwelt amongst us making Him first in significance and first in status. Jesus Christ is first in importance over all His creation, and at the name of Jesus every knee will bow for all creation is subject to His authority - and He died so that we might live.
Thank You Father that You sent Your only begotten Son into the world, which He made.. to become one of us, so that we might be reconciled back to Yourself and become children of God and joint-heirs with Christ, Who is the firstborn over all creation and before Whom we bow in reverend worship and praise for ever and ever, AMEN
