"The next day John sees Jesus coming. With the light of the glory of God resting upon him, the prophet stretches out his hands, declaring, “Behold the Lamb of God, which taketh away the sin of the world! This is He of whom I said, After me cometh a man which is become before me.... And I knew Him not; but that He should be made manifest to Israel, for this cause came I baptizing in water.... I have beheld the Spirit descending as a dove out of heaven; and it abode upon Him. And I knew Him not: but He that sent me to baptize in water, He said unto me, Upon whomsoever thou shalt see the Spirit descending, and abiding upon Him, the same is He that baptizeth with the Holy Spirit. And I have seen, and have borne witness that this is the Son of God.” John 1:29-34 , R. V., margin. DA 137.1"
"The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world."
The EGW passage directly quotes John 1:29 and other verses from the same chapter, attributing them to John the Baptist's declaration about Jesus.
"The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world. This is he of whom I said, After me cometh a man which is preferred before me: for he was before me. And I knew him not: but that he should be made manifest to Israel, therefore am I come baptizing with water. And John bare record, saying, I saw the Spirit descending from heaven like a dove, and it abode upon him. And I knew him not: but he that sent me to baptize with water, the same said unto me, Upon whom thou shalt see the Spirit descending, and remaining on him, the same is he which baptizeth with the Holy Ghost. And I saw, and bare record that this is the Son of God."
Ellen White directly references John 1:29-34 in this passage.
"Was this the Christ? With awe and wonder the people looked upon the One just declared to be the Son of God. They had been deeply moved by the words of John. He had spoken to them in the name of God. They had listened to him day after day as he reproved their sins, and daily the conviction that he was sent of Heaven had strengthened. But who was this One greater than John the Baptist? In His dress and bearing there was nothing that betokened rank. He was apparently a simple personage, clad like themselves in the humble garments of the poor. DA 137.2"
"For he shall grow up before him as a tender plant, and as a root out of a dry ground: he hath no form nor comeliness; and when we shall see him, there is no beauty that we should desire him."
Both passages describe Jesus' humble appearance and lack of outward signs of royalty or special status. The EGW passage highlights the contrast between the people's expectations and Jesus' actual presentation, echoing the sentiment in Isaiah 53:2 about his lack of comeliness.
"There were in the throng some who at Christ's baptism had beheld the divine glory, and had heard the voice of God. But since that time the Saviour's appearance had greatly changed. At His baptism they had seen His countenance transfigured in the light of heaven; now, pale, worn, and emaciated, He had been recognized only by the prophet John. DA 137.3"
"For he shall grow up before him as a tender plant, and as a root out of a dry ground: he hath no form nor comeliness; and when we shall see him, there is no beauty that we should desire him."
Both passages describe a change in Jesus' appearance, with Isaiah 53:2 focusing on his lack of physical beauty and the EGW passage describing his altered appearance after his baptism. The EGW passage uses the idea of a changed appearance to explain why some might not recognize him, echoing the sentiment in Isaiah.
"gentle and unassuming, He impressed men with a sense of power that was hidden, yet could not be wholly concealed. Was this the One for whom Israel had so long waited? DA 137.4"
"He is despised and rejected of men; a man of sorrows, and acquainted with grief: and we hid as it were our faces from him; he was despised, and we esteemed him not."
Both passages deal with the perception of Jesus and whether he was the Messiah. Isaiah 53:3 describes him as despised and rejected, while the EGW passage highlights the hidden power and the question of whether he was the one Israel awaited. There's a thematic connection regarding the expectations and perceptions surrounding Jesus.
