Let's check out some things that we would have heard from Jesus if we had lived at that time:
John 4:34 Jesus said to them: “My food is to do the will of him who sent me and to finish his work. 35 Do you not say that there are yet four months before the harvest comes? Look! I say to you: Lift up your eyes and view the fields, that they are white for harvesting. Already 36 the reaper is receiving wages and gathering fruit for everlasting life, so that the sower and the reaper may rejoice together. 37 For in this respect the saying is true: One is the sower and another the reaper. 38 I sent you to reap what you did not labor on. Others have labored, and you have entered into the benefit of their labor.”
... 5:30 I cannot do a single thing of my own initiative. Just as I hear, I judge, and my judgment is righteous because I seek, not my own will, but the will of him who sent me. 31 “If I alone bear witness about myself, my witness is not true. 32 There is another who bears witness about me, and I know that the witness he bears about me is true. (...) 34 However, I do not accept the witness from man, but I say these things so that you may be saved.
... 6:37 All those whom the Father gives me will come to me, and I will never drive away the one who comes to me; 38 for I have come down from heaven to do, not my own will, but the will of him who sent me. 39 This is the will of him who sent me, that I should lose none out of all those whom he has given me, but that I should resurrect them on the last day. 40 For this is the will of my Father, that everyone who recognizes the Son and exercises faith in him should have everlasting life, and I will resurrect him on the last day.”
... 7:14 When the festival was half over, Jesus went up into the temple and began teaching. 15 And the Jews were astonished, saying: “How does this man have such a knowledge of the Scriptures when he has not studied at the schools?” 16 Jesus, in turn, answered them and said: “What I teach is not mine, but belongs to him who sent me. 17 If anyone desires to do His will, he will know whether the teaching is from God or I speak of my own originality. 18 Whoever speaks of his own originality is seeking his own glory; but whoever seeks the glory of the one who sent him, this one is true and there is no unrighteousness in him. (...)27 On the contrary, we know where this man is from; yet when the Christ comes, no one is to know where he is from.” 28 Then as he was teaching in the temple, Jesus called out: “You know me and you know where I am from. And I have not come of my own initiative, but the One who sent me is real, and you do not know him. 29 I know him, because I am a representative from him, and that One sent me.” (...) 33 Jesus then said: “I will be with you a little while longer before I go to the One who sent me.
... 8:25 So they began to say to him: “Who are you?” Jesus replied to them: “Why am I even speaking to you at all? 26 I have many things to speak concerning you and to pass judgment on. As a matter of fact, the One who sent me is true, and the very things I heard from him I am speaking in the world.” 27 They did not grasp that he was talking to them about the Father. 28 Jesus then said: “After you have lifted up the Son of man, then you will know that I am he and that I do nothing of my own initiative; but just as the Father taught me, I speak these things. 29 And the One who sent me is with me; he did not abandon me to myself, because I always do the things pleasing to him.” (...) 42 Jesus said to them: “If God were your Father, you would love me, for I came from God and I am here. I have not come of my own initiative, but that One sent me.
... 12:44 However, Jesus called out and said: “Whoever puts faith in me puts faith not only in me but also in him who sent me; 45 and whoever sees me sees also the One who sent me. 46 I have come as a light into the world, so that everyone putting faith in me may not remain in the darkness. 47 But if anyone hears my sayings and does not keep them, I do not judge him; for I came, not to judge the world, but to save the world. 48 Whoever disregards me and does not receive my sayings has one to judge him. The word that I have spoken is what will judge him on the last day. 49 For I have not spoken of my own initiative, but the Father who sent me has himself given me a commandment about what to say and what to speak. 50 And I know that his commandment means everlasting life. So whatever I speak, I speak just as the Father has told me.”
Was Jesus telling someone that he was God?
