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(NASB)
The apostle John lays out some important historical and doctrinal truths in the first section of his gospel. He does this so that we may believe that Jesus is the Messiah, the Son of God so that by believing, we may have life in His name.
Having outlined the person of Christ, the incarnate Word of God Who would be rejected by His own people but accepted by all who would believe on His name, John gives increasing insight into the incarnation of Christ: "In the beginning was the Word, and the Word was with God and the Word was God..... and the Word became flesh and dwelt amongst us."
God dressed Himself in a body of human flesh for ever. He lived and died in a body. He rose and ascended in a body. He is currently sitting at the right hand of the Father in a glorified human body, and is one day returning to set up His kingdom clothed in the body of a perfect, sinless Man, the Word of God, dressed in human flesh.
The Word became flesh and lived His sinless life as the God-Man, but He remained fully God when He became fully Man. The eternal Son of God became the perfect Son of Man and was born into the fallen human race, fully Man yet retaining His eternal Deity so that He could save His people from their sins. Though He laid aside His glory for about thirty-three years, He remained fully God with undiminished Deity, for He is the eternal, omniscient, almighty Creator Who became perfect humanity and dwelt among us.
For 33-years, the God-Man tabernacled on earth. Born in Bethlehem, teaching and healing the people as He proclaimed His Messianic role before being crucified at Calvary, raised back to life and appearing to many in His resurrection body of flesh and bone, Jesus was indeed the only begotten Son of the Father. He was the unique 'God-Man' Who in His eternal Deity and perfect humanity, reflected the glory of God. Because He is the image and likeness of God, Jesus (the one and only unique God-Man) is the possessor of God's very character and essence - full of grace and truth.
Heavenly Father, thank You that in the beginning was the Word, and the Word was made flesh and came to dwell among us as the unique and only begotten Son of God, Who alone qualifies to be our Redeemer. Thank You that He was born into the human race as a man - fully God yet fully man - so that by His death and Resurrection, He could become the singular substitute for the sin of the world. Thank You that by grace through faith in Him, I have been redeemed. What a wonderful Saviour, full of grace and truth. To Him be all praise and glory, AMEN.
