'Believe' in the Bible

For seeing that in the wisdom of God, the world through its wisdom didn't know God, it was God's good pleasure through the foolishness of the preaching to save those who believe.

But if one of those who don't believe invites you to a meal, and you are inclined to go, eat whatever is set before you, asking no questions for the sake of conscience.

For first of all, when you come together in the assembly, I hear that divisions exist among you, and I partly believe it.

Therefore other languages are for a sign, not to those who believe, but to the unbelieving; but prophesying is for a sign, not to the unbelieving, but to those who believe.
