Except for those teenaged years. You know, those years where there I no record of him being anything but a teenager and young adult.
If Jesus is NOT God, his sacrifice was worthless and our faith is pointless.
What does Scripture say?
John 1:
1 In the beginning was the Word, and the Word was with God, and the Word was God. 2 The same was in the beginning with God. 3 All things were made by him; and without him was not any thing made that was made.
...
14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
John 8:
52 Then said the Jews unto him, Now we know that thou hast a devil. Abraham is dead, and the prophets; and thou sayest, If a man keep my saying, he shall never taste of death. 53 Art thou greater than our father Abraham, which is dead? and the prophets are dead: whom makest thou thyself? 54 Jesus answered, If I honour myself, my honour is nothing: it is my Father that honoureth me; of whom ye say, that he is your God: 55 Yet ye have not known him; but I know him: and if I should say, I know him not, I shall be a liar like unto you: but I know him, and keep his saying. 56 Your father Abraham rejoiced to see my day: and he saw it, and was glad. 57 Then said the Jews unto him, Thou art not yet fifty years old, and hast thou seen Abraham? 58 Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am. 59 Then took they up stones to cast at him: but Jesus hid himself, and went out of the temple, going through the midst of them, and so passed by.
Why, do you suppose, did they want to stone Him?
The answer should be obvious: He claimed as His own the Name of God.
Either He is God, or He was a blasphemer. There is no middle ground.
