The Father’s Witness
37 And the Father Himself, who sent Me, has testified of me. You have neither heard His voice at any time, nor seen His form. 38 But you do not have His word abiding in you, because whom He sent, Him you do not believe.
The supreme witness to the truth that is in Christ is found neither in human testimony, nor in the words of Jesus. Rather in the voice of God speaking to the human heart. When the Christian knows in his own heart that “the Father himself will borne witness of Christ.” then, the Christian possesses a certainty that surpasses all other assurances.
As Jesus spoke these words, perhaps He thought of that voice from heaven which was heard at His own baptism. Most of members of the Sanhedrin had heard the words of John and they had seen the works of Jesus. But of the third kind of testimony, the witness of the Father revealed to the heart, they knew nothing.
As Jesus had stated, “whom He has sent, you believe not” (vs 38). Hearing human testimony, observing the deeds of Jesus, may come before faith. Yet the supreme proof of the Messiahship and deity of Jesus Christ can be had only after faith has begun to grow. Only through the ear and the eye of faith can the Father be heard and seen. Only then can the word He speaks about Jesus Christ abide in man and understood by men. But when this word does abide in the heart and is understood, then there is no greater certainty of salvation and that Christ is the Messiah
