"Character of God Revealed in Christ Taking humanity upon Him, Christ came to be one with humanity, and at the same time to reveal our heavenly Father to sinful human beings. He who had been in the presence of the Father from the beginning, He who was the express image of the invisible God, was alone able to reveal the character of the Deity to mankind. He was in all things made like unto His brethren. He became flesh even as we are. He was hungry and thirsty and weary. He was sustained by food and refreshed by sleep. He shared the lot of men; yet He was the blameless Son of God. He was a stranger and sojourner on the earth—in the world, but not of the world; tempted and tried as men and women today are tempted and tried, yet living a life free from sin. Tender, compassionate, sympathetic, ever considerate of others, He represented the character of God, and was constantly engaged in service for God and man. MH 422"
"And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth."
Both passages discuss the incarnation of Christ, with John 1:14 stating that the Word became flesh and dwelt among us, and the EGW passage elaborating on the implications of Christ taking on humanity and revealing the Father.
"Wherefore in all things it behoved him to be made like unto his brethren, that he might be a merciful and faithful high priest in things pertaining to God, to make reconciliation for the sins of the people."
The EGW passage echoes the sentiment of Hebrews 2:17, focusing on Christ's incarnation and likeness to humanity. While not a direct quote, it expands on the idea of Christ becoming like us in all things.
"The unity that exists between Christ and His disciples does not destroy the personality of either. They are one in purpose, in mind, in character, but not in person. It is thus that God and Christ are one. MH 422.1"
"And now I am no more in the world, but these are in the world, and I come to thee. Holy Father, keep through thine own name those whom thou hast given me, that they may be one, as we are."
Both passages discuss the unity between Christ and believers, and between Christ and the Father. The EGW passage expands on the nature of this unity, drawing from the concept presented in John 17:11.
