Jn 12:36-40, Rom 10:15-16, Jn 1:10-12
In the Old Testament, Isaiah was surprised that no one believed that Christ suffered. (Isa 53:1)
Isa 53:1 Who hath believed our report? and to whom is the arm of the Lord revealed?
Although Christ Jesus performed many miracles, as the Old Testament prophesied, the Jews did not believe in Jesus as the Christ. (John 12:36-40, Romans 10:15-16)
John 12:36 While ye have light, believe in the light, that ye may be the children of light. These things spake Jesus, and departed, and did hide himself from them. 37 But though he had done so many miracles before them, yet they believed not on him: 38 That the saying of Esaias the prophet might be fulfilled, which he spake, Lord, who hath believed our report? and to whom hath the arm of the Lord been revealed? 39 Therefore they could not believe, because that Esaias said again, 40 He hath blinded their eyes, and hardened their heart; that they should not see with their eyes, nor understand with their heart, and be converted, and I should heal them.
Romans 10:15 And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things! 16 But they have not all obeyed the gospel. For Esaias saith, Lord, who hath believed our report?
Christ Jesus came to his land, but his people did not accept him as the Christ. However, those who accept Jesus as the Christ become children of God. (John 1:10-12, 1 John 5:1)
John 1:10 He was in the world, and the world was made by him, and the world knew him not. 11 He came unto his own, and his own received him not. 12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:
1 John 5:1 Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth him that begat loveth him also that is begotten of him.
