In Matthew 12:38-45, the pharisees came to Jesus and asked to show them a sign. Jesus said, you adulterous and perverse generation, no sign will be given to you except that of Jonah. He was in the belly of the whale for 3 days and nights. Jesus was pointing to His death and resurrection. Jesus used examples to teach them lessons. He said the men of Nineveh would rise up in judgment, because at the preaching of Jonah, they repented. Belief isn’t by what you see. It is by faith. Faith is the substance of things hoped for and the evidence of things not seen. Faith is not seeing but believing. Jesus wants us to believe. He showed us the way. Now it is up to us to trust that God will bring us home. The scary part is that the Israelites had the word of God and didn’t believe. Like God said, He used the gentiles to provoke Israel to jealousy. Because the gentiles readily accepted the gospel. Don’t ever think that your life in God is so firmly fixed, that He can’t shake you loose. Faith is the only thing that God wants from us. The rest He does.
