And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth.
John 1:14 (ESV)
If any act of God involves all Three Persons of the Godhead, then the Incarnation of the Son involves the entire Trinity. The Father sent the Son into the world in order to save the world and the Holy Spirit sustained the Son throughout His life until He completed His mission.
The Incarnation is the trinitarian God's way of revealing Himself to us in a personal way so that we can know Him and experience His eternal life of love.
As the Incarnate Word, Jesus possesses both a fully divine and fully human nature, which are inseparably and uniquely united in His person. Jesus is the true image of the invisible God born in human likeness. Instead of coming to us with His sovereign power, He came to us as a servant and as a child and yet affirming that He was divine. God made flesh.
Why is the Incarnation important?
It emphasises and demonstrates that our salvation is and has always been the free and gracious act of God. God had to become a man in order to save us. Although Jesus came to seek and save us, the good news does not stop there. We were not only forgiven of our sins but we were also transformed into new creations in Him, with the same righteousness as He. He took on our human nature so that we could share in His divine nature (2 Peter 1:4). It is through His life in us that we become by grace what God is by nature.
If the Incarnation affirms God’s love, then the Resurrection confirms God’s love. Jesus not only lived for us, but He also died for us and rose to life for us. The four gospels show us that the Son did not work alone. He completed His earthly ministry because the Father and the Holy Spirit were integrally and intimately working alongside Him.
It is through the Incarnation that we discover the amazing reality of “God with us.”
