John 5:33

30 Of myself I am unable to do anything: as the voice comes to me so I give a decision: and my decision is right because I have no desire to do what is pleasing to myself, but only what is pleasing to him who sent me.

31 If I gave witness about myself, my witness would not be true.

32 There is another who gives witness about me and I am certain that the witness he gives about me is true.

33 You sent to John and he gave true witness.

34 But I have no need of a man's witness: I only say these things so that you may have salvation.

35 He was a burning and shining light, and for a time you were ready to be happy in his light.

36 But the witness which I have is greater than that of John: the work which the Father has given me to do, the very work which I am now doing, is a witness that the Father has sent me.
