Abraham 1

 We learn that Abraham demonstrated great faith being faithful even as his family turned to idols.  Because of his faithfulness, he was chosen as were three virgins because they wouldn't bow down to the worship of idols, to be sacrificed.  The virgins were sacrificed.  As they were about to sacrifice Abraham - 

"...the priests laid violence upon me, that they might slay me also, as they did those virgins upon this altar;..."  Abraham 1:12

And as they lifted up their hands upon me, that they might offer me up and take away my life, behold, I lifted up my voice unto the Lord my God, and the Lord hearkened and heard, and he filled me with the vision of the Almighty, and the angel of his presence stood by me, and immediately unloosed my bands;

16 And his voice was unto me: Abraham, Abraham, behold, my name is Jehovah, and I have heard thee, and have come down to deliver thee, and to take thee away from thy father’s house, and from all thy kinsfolk, into a strange land which thou knowest not of;

17 And this because they have turned their hearts away from me, to worship the god of Elkenah, and the god of Libnah, and the god of Mahmackrah, and the god of Korash, and the god of Pharaoh, king of Egypt; therefore I have come down to visit them, and to destroy him who hath lifted up his hand against thee, Abraham, my son, to take away thy life.

18 Behold, I will lead thee by my hand, and I will take thee, to put upon thee my name, even the Priesthood of thy father, and my power shall be over thee.

19 As it was with Noah so shall it be with thee; but through thy ministry my name shall be known in the earth forever, for I am thy God."  Abraham 1:15-19

No question that this witness had an effect on Abraham the rest of his life.
