37 Even after Jesus had done all these miraculous signs in their presence, they still would not believe in him. 38 This was to fulfill the word of Isaiah the prophet:Without an eternal perspective, the cares of this world can overshadow the things that really matter.
"Lord, who has believed our message
and to whom has the arm of the Lord been revealed?"
39 For this reason they could not believe, because, as Isaiah says elsewhere:
40 "He has blinded their eyes
and deadened their hearts,
so they can neither see with their eyes,
nor understand with their hearts,
nor turn—and I would heal them." 41 Isaiah said this because he saw Jesus' glory and spoke about him.
42 Yet at the same time many even among the leaders believed in him. But because of the Pharisees they would not confess their faith for fear they would be put out of the synagogue; 43 for they loved praise from men more than praise from God.
44 Then Jesus cried out, "When a man believes in me, he does not believe in me only, but in the one who sent me. 45 When he looks at me, he sees the one who sent me. 46 I have come into the world as a light, so that no one who believes in me should stay in darkness.
47 "As for the person who hears my words but does not keep them, I do not judge him. For I did not come to judge the world, but to save it. 48 There is a judge for the one who rejects me and does not accept my words; that very word which I spoke will condemn him at the last day. 49 For I did not speak of my own accord, but the Father who sent me commanded me what to say and how to say it. 50 I know that his command leads to eternal life. So whatever I say is just what the Father has told me to say."
This is an example of the Son and the Father being One, and yet being distinct. If you see the Son, you have seen the Father. Yet, the Son does not condemn, but saves from the wrath of the Father.
