John 5:30-38 I can of mine own self do nothing: as I hear, I judge: and my judgment is just; because I seek not mine own will, but the will of the Father which hath sent me. If I bear witness of myself, my witness is not true. There is another that bears witness of me; and I know that the witness which he witness of me is true. You sent unto John, and he bare witness unto the truth. But I receive not testimony from man: but these things I say, that you might be saved. He was a burning and a shining light: and you were willing for a season to rejoice in his light. But I have greater witness than that of John: for the works which the Father hath given me to finish, the same works that I do, bear witness of me, that the Father hath sent me. And the Father himself, which hath sent me, hath borne witness of me. You have neither heard his voice at any time, nor seen his shape. And you have not his word abiding in you: for whom he hath sent him you believe not.
The Son can do nothing of Himself (John 5:17,19, 30; 8:18, 28); He seeks not His own will, but the will of the Father (John 6:38); His doctrine is not His, but the Father’s who sent Him (John 7:16; 8:26,38).John 5:31
‘If I bear witness of myself, my witness is not true.’ For a witness to be legally true and acceptable there must be two or three witnesses (Deut. 17:6).
‘Another that bear witness of me’ this refers to the Father (John 7:28; 8:26; Mat. 3:17; 17:5). He did not here refer to John the Baptist who also witnessed of Him (John 5:33-35), but to the Father and the works which are greater witnesses than John (John 5:36-38).
John the Baptist ‘was a burning and a shining light’ which was a common rabbinic idiom for a famous man; the Jews rejoiced in him for a season, thus did they believed John to be a prophet. A prophet cannot lie, so why didn’t they believe what John said of Christ (John 1:29)?
‘You have neither heard His voice at any time nor seen His shape.’ – You Jews here today have never heard the Father’s voice as did Israel at Sinai (Deut. 5:22-33 and others in Mat. 3:17; 17:5); nor have you seen His shape as men in other ages have seen His physical form (Gen. 18:1-8; 32:24-30; Exo. 24:9-11; Jos. 5:13-15; Jdg. 6:11-23; 13:3-23; etc). This proves that God has both a voice and a bodily shape.
