31 “If I testify about myself, my witness is not valid. 32 It is another who testifies about me. I know that the testimony which he testifies about me is true. 33 You have sent to John, and he has testified to the truth. 34 But the testimony which I receive is not from man. However, I say these things that you may be saved. 35 He was the burning and shining lamp, and you were willing to rejoice for a while in his light. 36 But the testimony which I have is greater than that of John, for the works which the Father gave me to accomplish, the very works that I do, testify about me, that the Father has sent me. 37 The Father himself, who sent me, has testified about me. You have neither heard his voice at any time, nor seen his form."

John 5:31-17 - World English Bible

After he proclaimed his mission as that of the Father (to raise the dead), Jesus shifted his monologue to the veracity of his claim. Truth of an assertion in Jewish courts required the testimony of two witnesses. What he claimed about himself was not enough. The Baptist testified about him, but there was even a greater testimony: what the Father said about him, expressed in the works he performed. None of his opponents had ever seen God or heard his voice, but the Father had been revealed through the mission of his Son.

We know God through our faith in his Son. We experience God today through the activity of the body of Christ, his Church, in worship and acts of social charity. Not only do we experience God in this way, we show others the Father, just as Jesus did two thousand years ago.

When was the last time you experience God? Was it at Mass or in the good others did for you?
