" Verily, verily, I say unto you, If a man keep
my saying, he shall never see death."
John 8:51

This puzzled them. Abraham and the prophets
were dead. So how could Jesus say this?

Their spiritual vision was so darkened that what
Jesus said was all a mystery. He added to it by
saying "Your father Abraham rejoiced to see my
day: and he saw it, and was glad." John 8:56
