John 12:28 Meaning

26If any man serve me, let him follow me; and where I am, there shall also my servant be: if any man serve me, him will my Father honour.

27Now is my soul troubled; and what shall I say? Father, save me from this hour: but for this cause came I unto this hour.

28Father, glorify thy name. Then came there a voice from heaven, saying, I have both glorified it, and will glorify it again.

29The people therefore, that stood by, and heard it, said that it thundered: others said, An angel spake to him.

30Jesus answered and said, This voice came not because of me, but for your sakes.
