4 Bible Verses about Incredulity

But Thomas, one of the twelve, called Didymus, was not with them when Jesus came.

behold, I will put a fleece of wool on the threshing-floor. If there be dew on the fleece only, and it be dry upon all the ground, then I shall know that thou will save Israel by my hand as thou have spoken. And it was so, for he rose up early on the morrow, and pressed the fleece together, and wrung the dew out of the fleece, a bowlful of water. And Gideon said to God, Let not thine anger be kindled against me, and I will speak but this once. Let me make trial, I pray thee, but this once with the fleece. Let it now be dry only upon the fleece, and upon all the ground let tread more.
And God did so that night, for it was dry upon the fleece only, and there was dew on all the ground.

They brought him to the Pharisees--the former blind man. Now it was a Sabbath when Jesus made the clay and opened his eyes. Again therefore the Pharisees also asked him how he received sight. And he said to them, He put clay upon my eyes, and I washed, and I see.read more.
Therefore some of the Pharisees said, This man is not from God, because he does not keep the Sabbath. Other men said, How is a sinful man able to do such signs? And there was division among them. They say again to the blind man, What do thou say about him, that he opened thine eyes? And he said, He is a prophet. The Jews therefore did not believe about him, that he had been blind, and had received sight, until they called the parents of the man who had received sight. And they asked them, saying, Is this your son, whom ye say that he was born blind? How then does he now see? And his parents answered them and said, We know that this is our son, and that he was born blind, but how he now sees, we know not. Or who opened his eyes, we know not. He has maturity, ask him. He will speak for himself. His parents spoke these things because they feared the Jews, for the Jews had agreed already, that if any man confessed him as Christ, he should become excommunicated from the synagogue. Because of this his parents said, He has maturity, ask him. So they called the man who was blind, for a second time, and said to him, Give glory to God. We know that this man is sinful. That man therefore answered and said, If he is sinful, I know not. One thing I know, that being blind, now I see. But again they said to him, What did he do to thee? How did he open thine eyes? He answered them, I told you already, and ye did not listen. Why do ye want to hear it again? Do ye not also want to become his disciples? They reviled him, and said, Thou are a disciple of that man, but we are disciples of Moses. We know that God has spoken to Moses, but this man, we know not where he is from. The man answered and said to them, For in this it is amazing, that ye know not where he is from, and yet he opened my eyes. And we know that God does not listen to sinners, but if any man is a worshiper of God, and does his will, he listens to this man. From the age, it was not heard that any man opened the eyes of a man who was born blind. If this man were not from God, he could do nothing. They answered and said to him, Thou were born entirely in sins, and thou teach us. And they cast him outside. Jesus heard that they cast him outside. And having found him, he said to him, Do thou believe in the Son of God? That man answered and said, And who is he, Lord, that I may believe in him? And Jesus said to him, Thou have both seen him, and he is that man who speaks with thee. And he affirmed, Lord, I believe. And he worshiped him. And Jesus said, For judgment I came into this world, so that those not seeing might see, and those who see might become blind. And those of the Pharisees who were with him heard these things, and they said to him, Are we also blind? Jesus said to them, If ye were blind, ye would have no sin, but now ye say, We see, therefore your sin remains.

But we think it worthy to hear from thee what thou think. For indeed about this sect, it is known to us that everywhere it is spoken against. And having appointed a day for him, more came to him into his lodging, to whom he expounded, solemnly testifying the kingdom of God, and persuading them of the things about Jesus, both from the law of Moses and the prophets, from m And some were convinced by the things that were spoken, and some disbelieved.read more.
And being discord among each other, they departed after Paul spoke one thing, saying, Well spoke the Holy Spirit through Isaiah the prophet to our fathers, saying, Go thou to this people, and say, Hearing ye will hear, and will, no, not understand, and seeing ye will see, and will, no, not perceive. For this people's heart was made fat, and they hear heavily with the ears. And they shut their eyes, lest they may perceive with the eyes, and hear with the ears, and understand with the heart, and should turn, and I would heal the Be it known to you therefore, that the salvation of God was sent to the Gentiles, and they will hear. And when he said these things, the Jews departed, having much disputing among themselves.
