'Believe' in the Bible

so that you became an example to all those who believe in Macedonia and in Achaia,

You [are] witnesses, and [so is] God, how devoutly and righteously and blamelessly we became to you who believe,

And because of this we also give thanks to God constantly, that [when you] received God's word {that you heard} from us, you accepted [it] not [as the] word of men, but as [it] truly is, [the] word of God, which also is at work in you who believe.

For if we believe that Jesus died and rose [again], thus also God will bring those who have fallen asleep through Jesus together with him.
