"to heed the call to repentance. Thus they had hardened their hearts and darkened their understanding. When Heaven bore testimony to Jesus at His baptism, they perceived it not. Eyes that had never been turned in faith to Him that is invisible beheld not the revelation of the glory of God; ears that had never listened to His voice heard not the words of witness. So it is now. Often the presence of Christ and the ministering angels is manifest in the assemblies of the people, and yet there are many who know it not. They discern nothing unusual. But to some the Saviour's presence is revealed. Peace and joy animate their hearts. They are comforted, encouraged, and blessed. DA 136.1"
"For this people’s heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should heal them."
Both passages discuss the inability of some people to perceive spiritual truth due to hardened hearts and closed minds. The EGW passage amplifies this idea in the context of Jesus' baptism.
"The deputies from Jerusalem had demanded of John, “Why baptizest thou?” and they were awaiting his answer. Suddenly, as his glance swept over the throng, his eye kindled, his face was lighted up, his whole being was stirred with deep emotion. With outstretched hands he cried, “I baptize in water: in the midst of you standeth One whom ye know not, even He that cometh after me, the latchet of whose shoe I am not worthy to unloose.” John 1:26, 27 , R. V., margin. DA 136.2"
"John answered them, saying, I baptize with water: but there standeth one among you, whom ye know not;"
The EGW passage directly quotes John 1:26, setting the context and highlighting its significance.
"The message was distinct and unequivocal, to be carried back to the Sanhedrin. The words of John could apply to no other than the long-promised One. The Messiah was among them! In amazement priests and rulers gazed about them, hoping to discover Him of whom John had spoken. But He was not distinguishable among the throng. DA 136.3"
"John answered them, saying, I baptize with water: but there standeth one among you, whom ye know not;"
The EGW passage directly references the idea that the Messiah was present but not immediately recognizable, echoing John 1:26.
When at the baptism of Jesus, John pointed to Him as the Lamb of God, a new light was shed upon the Messiah's work. The prophet's mind was directed to the words of Isaiah, “He is brought as a lamb to the slaughter.” Isaiah 53:7 . During the weeks that followed, John with new interest studied the prophecies and the teaching of the sacrificial service. He did not distinguish clearly the two phases of Christ's work,—as a suffering sacrifice and a conquering king,—but he saw that His coming had a deeper significance than priests or people had discerned. When he beheld Jesus among the throng on His return from the desert, he confidently looked for Him to give the people some sign of His true character. Almost impatiently he waited to hear the Saviour declare His mission; but no word was spoken, no sign given. Jesus did not respond to the Baptist's announcement of Him, but mingled with the disciples of John, giving no outward evidence of His special work, and taking no measures to bring Hims…
"He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth."
The EGW passage explicitly quotes Isaiah 53:7 and discusses its connection to John the Baptist's understanding of Jesus as the Lamb of God.
