3 Bible Verses about Incredulity

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

They bring to the Pharisees the man who had aforetime been blind. (It was the sabbath, when Jesus made the clay and opened his eyes.) Again the Pharisees also asked him, How he had received his sight? He said to them, He put clay on my eyes, and I washed, and see.read more.
Therefore said some of the Pharisees, This man is not of God, because he keepeth not the sabbath. Others said, How can a man that is a sinner, do such miracles? And there was a division among them. They say to the blind man again, What sayest thou of him, for that he hath opened thine eyes? He said, He is a prophet. But the Jews did not believe concerning him, that he had been blind and received his sight, till they had called the parents of him who had received his sight. And they asked them, saying, Is this your son, who ye say was born blind? How then doth he now see? His parents answered them, and said, We know that this is our son, and that he was born blind. But how he now seeth, we know not, or who hath opened his eyes, we know not. He is of age: ask him; he will speak concerning himself. His parents said this, because they feared the Jews; for the Jews had already agreed, That if any man should own him to be Christ, he should be put out of the synagogue. Therefore said his parents, He is of age; ask him. Therefore they called a second time the man that had been blind, and said to him, Give glory to God; we know that this man is a sinner. He answered and said, That he is a sinner I know not: one thing I know, that I was blind, and now see. They said to him again, What did he to thee? How opened he thine eyes? He answered them, I have told you already, and ye did not hearken: why would ye hear it again? Are ye also willing to be his disciples? Then they reviled him and said, Thou art a disciple of that fellow; but we are disciples of Moses. We know that God spake to Moses; but we know not this fellow, whence he is. The man answered and said to them, Why herein is a marvellous thing, that ye know not whence he is; altho' he hath opened my eyes! We know that God heareth not sinners; but if a man be a worshiper of God, and do his will, him he heareth. Since the world began it was not heard, that any man opened the eyes of one that was born blind. If this man were not of God, he could do nothing. They answered and said to him, Thou-wast altogether born in sins, and dost thou teach us? And they cast him out. Jesus heard that they had cast him out; and having found him, he said to him, Dost thou believe on the Son of God? He answered and said, Sir, who is he, that I may believe on him? Jesus said to him, Thou hast both seen him, and he that talketh with thee is he. And he said, Lord, I believe. And he worshiped him. Jesus said, For judgment am I come into the world, that they who see not, may see, and that they who see, may become blind. And some of the Pharisees that were with him heard this, and said to him, Are we blind also? Jesus said to them, If ye had been blind, ye would have had no sin. But now ye say, We see: therefore your sin remaineth.

But we desire to hear of thee what thou thinkest; for concerning this sect, we know, that it is every where spoken against. And having appointed him a day, many came to him at his lodging, to whom he expounded the kingdom of God, testifying and persuading them concerning Jesus, both from the law of Moses and the prophets, from morning till evening. And some believed the things that were spoken, and some believed not.read more.
And not agreeing with each other, they brake up the assembly, after Paul had spoken one word, Well spake the Holy Ghost by the prophet Isaiah to your fathers, Saying, Go to this people and say, Hearing ye shall hear, and shall not understand, and seeing ye shall see, and shall not perceive. For the heart of this people is waxed gross, and with their ears they hear heavily, and their eyes have they closed; lest they should see with their eyes, and hear with their ears, and understand with their hearts, and should be converted, and I should heal them. Be it known therefore unto you, that the salvation of God is sent to the Gentiles, and they will hear. And when he had said these things, the Jews departed, having great debating with each other.
