Father, glorify your name. Then came there a voice from heaven, saying, I have both glorified it and will glorify it again. The people therefore that stood by, and heard it, said it thundered.
"That was the voice of God, and was perfectly intelligible to Jesus, but to the others it sounded like thunder.
Q: Why?
A: Simply because they did not understand the voice of God; they were not sufficiently acquainted with Him to recognize His voice, and so to them it was only a loud noise.
The Lord is now speaking in the ears of the people a message of salvation.
