What does John 5:43 mean?
This comment follows the same argument Jesus has made in prior verses. First-century Jewish religious authorities were given more reasons to believe in Jesus than anyone. They spoke to John the Baptist (John 5:33). They saw Jesus' miracles (John 5:36). They had extensive knowledge of the written Word of God (John 5:39). The problem was not that these men could not come to faith in Christ, or that they were not convinced. Rather, they willfully will not do so (John 5:40).Yet these same Jewish religious leaders were willing to accept false teachers. They were happy to have the approval of other men and other self-styled gurus. And yet, they were not willing to follow the evidence God has given to the right conclusion. When other, lesser men come, they are accepted. When Jesus comes, in the name of God the Father, these men reject Him. This is not a problem of the mind, but of the will. They don't accept Jesus because they refuse to, regardless of what other excuses they may offer (Luke 16:31).
