In context
29and come out — those who have done good, to a resurrection of life; those who have done evil, to a resurrection of judgment. 30I can do nothing on my own. I judge as I hear, and my judgment is just, because I do not seek my own will but the will of the one who sent me. 31If I testify about myself, my testimony is not valid. 32There is another who testifies about me, and you know that the testimony he gives about me is true. 33You sent to John, and he has testified to the truth.
