'Believer' in the Bible

He also came to Derbe and to Lystra. A disciple named Timothy was there, the son of a Jewish woman who was a believer, but whose father was a Greek.

After she and her household were baptized, she urged us, "If you consider me to be a believer in the Lord, come and stay in my house." And she persuaded us.

To the rest I say -- I, not the Lord -- if a brother has a wife who is not a believer and she is happy to live with him, he should not divorce her.

And if a woman has a husband who is not a believer and he is happy to live with her, she should not divorce him.

And what agreement does Christ have with Beliar? Or what does a believer share in common with an unbeliever?

So then those who believe are blessed along with Abraham the believer.

Now the believer of humble means should take pride in his high position.

Do not speak against one another, brothers and sisters. He who speaks against a fellow believer or judges a fellow believer speaks against the law and judges the law. But if you judge the law, you are not a doer of the law but its judge.
