'Heirs' in the Bible

For if those of the law [are] heirs, faith is rendered void and the promise is nullified.

and if children, also heirs--heirs of God and fellow heirs with Christ, if indeed we suffer together [with him] so that we may also be glorified together [with him].

And if you [are] Christ's, then you are descendants of Abraham, heirs according to the promise.

so that, having been justified by his grace, we may become heirs according to the hope of eternal life.

In the same way God, [because he] wanted to show even more to the heirs of the promise the unchangeableness of his resolve, guaranteed [it] with an oath,

Listen, my dear brothers! Did not God choose the poor of the world [to be] rich in faith, and heirs of the kingdom that he has promised to those who love him?
