'Believers' in the Bible

[and besides this evidence] God also testifying with them [confirming the message of salvation], both by signs and wonders and by various miracles [carried out by Jesus and the apostles] and by [granting to believers the] gifts of the Holy Spirit according to His own will.

For we [believers] have become partakers of Christ [sharing in all that the Messiah has for us], if only we hold firm our newborn confidence [which originally led us to Him] until the end,

For although, considering the long time you have been believers, you ought now to be teachers of others, you really need some one to teach you over again the very rudiments of the truths of God, and you have come to require milk instead of solid food.

not forsaking our meeting together [as believers for worship and instruction], as is the habit of some, but encouraging one another; and all the more [faithfully] as you see the day [of Christ’s return] approaching.

Let love of your fellow believers continue.

Give our greetings to all of your [spiritual] leaders and to all of the saints (God’s people). Those [Christians] from Italy send you their greetings.
