'Unbelieving' in the Bible

They have been unfaithful to the LORD, having raised unbelieving children. In the coming month they will be devoured, along with their fields.

Jesus replied, "You unbelieving and perverted generation! How long must I be with you? How long must I put up with you? Bring him here to me!"

Jesus told them, "You unbelieving generation! How long must I be with you? How long must I put up with you? Bring him to me!"

Jesus answered, "You unbelieving and perverted generation! How much longer must I be with you and put up with you? Bring your son here!"

Instead, one brother goes to court against another brother, and before unbelieving judges, at that!

For the unbelieving husband has been sanctified because of his wife, and the unbelieving wife has been sanctified because of her husband. Otherwise, your children would be unclean, but now they are holy.

But if the unbelieving partner leaves, let him go. In such cases the brother or sister is not under obligation. God has called you to live in peace.

Everything is clean to those who are clean, but nothing is clean to those who are corrupt and unbelieving. Indeed, their very way of thinking and their consciences have been corrupted.

See to it, my brothers, that no evil, unbelieving heart is found in any of you, as shown by your turning away from the living God.
