Hebrews 11:17 By faith Abraham, when he was tried, offered up Isaac: and he that had received the promises offered up his only begotten son, 11:18 Of whom it was said, That in Isaac shall thy seed be called: 11:19 Accounting that God was able to raise him up, even from the dead; from whence also he received him in a figure.
That was the "My day" that Abraham had rejoiced to see - his own resurrection one day.
John 8:51 Verily, verily, I say unto you, If a man keep my saying, he shall never see death. 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. 8:53 Art thou greater than our father Abraham, which is dead? and the prophets are dead: whom makest thou thyself? 8:54 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: 8:55 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. 8:56 Your father Abraham rejoiced to see my day: and he saw it, and was glad. 8:57 Then said the Jews unto him, Thou art not yet fifty years old, and hast thou seen Abraham? 8:58 Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am. 8:59 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.
Matthew 22:28 Therefore in the resurrection whose wife shall she be of the seven? for they all had her. 22:29 Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God. 22:30 For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven. 22:31 But as touching the resurrection of the dead, have ye not read that which was spoken unto you by God, saying, 22:32 I am the God of Abraham, and the God of Isaac, and the God of Jacob? God is not the God of the dead, but of the living.
Before Abraham was, I AM...not the God of the dead, but of the living.
John 11:23 Jesus saith unto her, Thy brother shall rise again. 11:24 Martha saith unto him, I know that he shall rise again in the resurrection at the last day. 11:25 Jesus said unto her, I am the resurrection, and the life: he that believeth in me, though he were dead, yet shall he live: 11:26 And whosoever liveth and believeth in me shall never die. Believest thou this? 11:27 She saith unto him, Yea, Lord: I believe that thou art the Christ, the Son of God, which should come into the world.
John 8:37 I know that ye are Abraham's seed; but ye seek to kill me, because my word hath no place in you. 8:38 I speak that which I have seen with my Father: and ye do that which ye have seen with your father. 8:39 They answered and said unto him, Abraham is our father. Jesus saith unto them, If ye were Abraham's children, ye would do the works of Abraham. 8:40 But now ye seek to kill me, a man that hath told you the truth, which I have heard of God: this did not Abraham. 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.
