The Son is the image of the invisible God, the firstborn over all creation. Colossians 1:15
Jesus is the image of God, the Word that became flesh. Think about it before Jesus came to Earth, nobody knew what God looked like. Before at the Holy Temple, there was a veil that separated people from God. Only the high priest was permitted to pass beyond that veil (Hebrews 9:7) But when Jesus was born and took the cross all our sins that veil has been torn (Matthew 27)
The birth of Jesus means so many things to us, one thing is it brought us a personal relationship with our Creator and Heavenly Father. Anyone who has seen Jesus has seen God (John 14:9) Jesus is the image of God, the Nativity story shows us how God works in mysterious ways, he is in complete control.
Jesus is the firstborn over all creation, meaning if you want eternal life it comes through Jesus Christ. He was born of a virgin to take away the sins of the world. Jesus was here before Creation, for by him all things were created (Colossians 1:16) but he lowered himself below the angels to take our sins and eventually taste death.
So rejoice this Christmas season, for Christ was born, Jesus the image of God came here to save you and give you eternal life. Accept this gift of grace and mercy in Jesus Name Amen
