John 5:33-36

In fact, you sent investigators to listen to John the Baptist, and his testimony about me was true. Of course, I have no need of human witnesses, but I say these things so you might be saved. John was like a burning and shining lamp, and you were excited for a while about his message. But I have a greater witness than John—my teachings and my miracles. The Father gave me these works to accomplish, and they prove that he sent me.
