scripture
Matthew 16:1 The Pharisees and Sadducees came to Jesus and tested him by asking him to show them a sign from heaven.
2 He replied, “When evening comes, you say, ‘It will be fair weather, for the sky is red,’ 3 and in the morning, ‘Today it will be stormy, for the sky is red and overcast.’ You know how to interpret the appearance of the sky, but you cannot interpret the signs of the times. 4 A wicked and adulterous generation looks for a miraculous sign, but none will be given it except the sign of Jonah.” Jesus then left them and went away.
observation
What do you mean you want a sign from heaven? Where have you Pharisees and Sadducees been?
Wasn’t feeding a large crowd out of almost nothing a sign? And doing it on two different occasions? How about turning water into wine? (Matthew 14:15, 15:32, John 2:1)
Wasn’t healing a leper, a paralyzed, the blind and thousands of other healing's a pretty good sign?
Casting demons out and having them acknowledge Jesus as the Son of God, wasn’t that an acceptable sign? (Matthew 8:29)
Wasn’t bringing the dead back to life pretty awesome? (Matthew 9:18)
How about walking on water? (Matthew 14:22)
But then there is the largest sign of all, the sign of the prophet Jonah:
Matthew 12:39 He answered, “A wicked and adulterous generation asks for a miraculous sign! But none will be given it except the sign of the prophet Jonah. 40 For as Jonah was three days and three nights in the belly of a huge fish, so the Son of Man will be three days and three nights in the heart of the earth.
So much irrefutable evidence and still so many millions will not believe, what more could he have done to make it more obvious that he is the Messiah?
Romans 1:20 For since the creation of the world God's invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that men are without excuse.
