'Believers' in the Bible

As a result, you became an example to all the believers in Macedonia and Achaia.

You are witnesses, and so is God, of how devoutly, righteously, and blamelessly we conducted ourselves with you believers.

to live lives [of honor, moral courage, and personal integrity] worthy of the God who [saves you and] calls you into His own kingdom and glory.

This is why we constantly thank God, because when you received the message about God that you heard from us, you welcomed it not as a human message, but as it truly is, the message of God, which also works effectively in you believers.
