And the Word became flesh and dwelt among us, and we saw His glory, glory as of the only begotten from the Father, full of grace and truth. - John 1:14
The Gospel of John opens with a description of Jesus as the Word of God. He was in the beginning with God and was God. All of creation came through Him, and He is the light of the world.
In verse 14, the Apostle John, one of the twelve disciples, gives us two important promises about Jesus.
The first is that God became flesh. The creator God stepped into His creation. He took on our form and walked among us and experienced our world. In doing so, He understands the struggles and problems each of us face.
Where all other religions require people to sacrifice and work to be good enough for God, Christianity has God stepping down to our level.
The second promise is about the uniqueness of Jesus.
