John 12:20-36 KJV

20 And there were certain Greeks among them that came up to worship at the feast:
23 And Jesus answered them, saying,The hour is come, that the Son of man should be glorified.
24 Verily, verily, I say unto you, Except a corn of wheat fall into the ground and die, it abideth alone: but if it die, it bringeth forth much fruit.
25 He that loveth his life shall lose it; and he that hateth his life in this world shall keep it unto life eternal.
29 The people therefore, that stood by, and heard it, said that it thundered*: others said, An angel spake to him.
32 And I, if I be lifted up from the earth, will draw all men unto me.
34 The people answered him, We have heard out of the law that Christ abideth for ever: and how sayest thou*,The Son of man must be lifted up? who is this Son of man?
36 While ye have light, believe in the light, that ye may be the children of light. These things spake Jesus, and departed, and did hide himself from them.
