Some of Jesus’ biggest critics and skeptics were the Pharisees. They were a religious sect famous for their strict adherence to the Old Testament laws. They were powerful and influential leaders who may have been threatened by the popularity of Jesus.
One of the laws they followed was about testimony only being accepted when validated by two witnesses, and they criticized Jesus for not offering more testimonial truth (evidently his miracles and teachings were not enough for them)! Jesus’ answer reminds us that we should never hold God to a standard higher than himself. He along with his goodness, his power, his miracles, and his word are the only testimony we need.
(John 8:13-18) 13 The Pharisees challenged him, “Here you are, appearing as your own witness; your testimony is not valid.” 14 Jesus answered, “Even if I testify on my own behalf, my testimony is valid, for I know where I came from and where I am going. But you have no idea where I come from or where I am going.
15 You judge by human standards; I pass judgment on no one. 16 But if I do judge, my decisions are true, because I am not alone. I stand with the Father, who sent me. 17 In your own Law it is written that the testimony of two witnesses is true. 18 I am one who testifies for myself; my other witness is the Father, who sent me.”
