When asked by the Pharisees for miraculous proof that He was indeed the Messiah, Jesus answered them by saying that none would be given except the “sign of Jonah.” Jesus recognized the religious leaders’ hardness of heart and refused to give them further proof of His identity. It wasn’t long after this encounter that Jesus made his triumphal entry into Jerusalem. The leadership turned up the fire on Jesus and was successful in ending His ministry—and His life. But the “sign of Jonah” would turn out to be Jesus’ greatest miracle of all. His resurrection from the dead would be God’s primary sign that Jesus was Israel’s long-awaited Messiah and would establish Christ’s claims of deity. Even after this, many in leadership still did not believe in Jesus as the Christ and prevented others from doing so. We need to help others overcome anything that would hinder them from putting their faith in Jesus.
