Want to know the future; don't read this paper. There is not going to be a flood...right! We humans are always fascinated by "inside knowledge" because it is a form of power. But when it comes to matters of religion, we already have everything we need to know. Yet the religious leaders came to Jesus asking for a sign; Why?
Matthew 16:1-4 WEB (R)
(1) The Pharisees and Sadducees came, and testing him, asked him to show them a sign from heaven.
(2) But he answered them, "When it is evening, you say, 'It will be fair weather, for the sky is red.'
(3) In the morning, 'It will be foul weather today, for the sky is red and threatening.' Hypocrites! You know how to discern the appearance of the sky, but you can't discern the signs of the times!
(4) An evil and adulterous generation seeks after a sign, and there will be no sign given to it, except the sign of the prophet Jonah." He left them, and departed.
If there is a lot of water, there may be a flood; daa! Still, some people will say there is no flood, even when the waters are up to their knees. Jesus had told the religious leaders who he was and performed many miracles before chapter sixteen, but that wasn't enough. So, why were they asking again? Because they wanted to find fault with him; to discredit him because they really did not WANT TO BELIEVE. This was a sign of their evil heart and lack of spiritual perception. Truth is, we believe exactly what we want to, nothing more, nothing less.
