Was Jesus Trustworthy?
When Christ spoke to a group of hostile Jews in Jerusalem regarding God the Father and His own equality with Him (John 5:17-30; cf. 10:30), He defended His deity by pointing to several witnesses, including John the Baptist, the Father in heaven, and the Scriptures (5:33-47). One statement that has confused some Bible readers concerning Jesus’ defense of His deity is found in John 5:31. Jesus began this part of His discourse by saying, “If I bear witness of Myself, My witness is not true” (emp. added). According to many Bible critics, this declaration blatantly contradicts the following statement that He made on another occasion when speaking to the Pharisees. Christ said: “Even if I bear witness of Myself, My witness is true” (John 8:14, emp. added). How could He say that His witness was both true, and not true, without being contradictory?
By way of an answer, consider the following illustration. An innocent man on trial for murder is judged to be guilty by the jury, even after proclaiming his innocence. (Someone had framed the defendant for the murder, and all of the evidence the jury heard pointed to the defendant as the offender.) When leaving the court house, if the man who was wrongly convicted is asked by a newspaper reporter, “Are you guilty?,” and he responds by saying, “If the court says I’m guilty, I’m guilty,” has the man lied? Even though the statements, “I am guilty,” and “I am not guilty,” are totally different, they may not be contradictory, depending on the time and sense in which they are spoken. After the trial, the wrongly accused defendant simply repeated the jury’s verdict. He said, “I am guilty,” and meant, “The court has found me guilty.”
When Jesus conceded to the Jews the fact that His witness was “not true,” He was not confessing to being a liar. Rather, Jesus was reacting to a well-known law of His day. In Greek, Roman, and Jewish law, the testimony of a witness could not be received in his own case (see Robertson, 1997). “Witness to anyone must always be borne by someone else” (Morris, 1995, p. 287). The Law of Moses declared: “One witness shall not rise against a man concerning any iniquity or any sin that he commits; by the mouth of two or three witnesses the matter shall be established” (Deuteronomy 19:15; cf. Matthew 18:15-17). The Pharisees understood this law well, as is evident by their statement to Jesus: “You bear witness of Yourself; Your witness is not true” (John 8:13). In John 5:31, “Jesus points to the impossibility of anyone’s being accepted on the basis of his own word…. He is asserting that if of himself he were to bear witness to himself, that would make it untrue” in a court of law (Morris, p. 287). If Jesus had no evidence in a trial regarding His deity other than His own testimony about Himself, His testimony would be inconclusive. Jesus understood that His audience had a right to expect more evidence than just His word. Similar to the illustration given earlier where an innocent person accepts the guilty verdict of the jury as final, Jesus said, “My witness is not true,” and meant that, in accordance with the law, His own testimony apart from other witnesses would be considered invalid (or insufficient to establish truth).
But why is it that Jesus said to the Pharisees at a later time that His “witness is true” (John 8:14)? The difference is that, in this instance, Jesus was stressing the fact that His words were true. Even if in a court of law two witnesses are required for a fact to be established (a law Jesus enunciated in verse 17), that law does not negate the fact that Jesus was telling the truth, just as it did not negate the fact that the wrongly accused man mentioned above was telling the truth during his trial. Jesus declared His testimony to be true for the simple reason that His testimony revealed the true facts regarding Himself (Lenski, 1961, p. 599). He then followed this pronouncement of truth with the fact that there was another witness—the Father in heaven Who sent Him to Earth (8:16-18). Thus, in actuality, His testimony was true in two senses: (1) it was true because it was indeed factual; and (2) it was valid because it was corroborated by a second unimpeachable witness—God.
God the Father (John 8:18; 5:37-38), along with John the Baptist (John 5:33), the miracles of Jesus (5:36), the Scriptures (5:39), and specifically the writings of Moses (5:46), all authenticated the true statements Jesus made regarding His deity. Sadly, many of His listeners rejected the evidence then, just as people reject it today.
