'Heirs' in the Bible

For if they that are of the law are heirs, faith is made void, and the promise is made of none effect:

and if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him , that we may be also glorified with him .

And if ye are Christ's, then are ye Abraham's seed, heirs according to promise.

that, being justified by his grace, we might be made heirs according to the hope of eternal life.

Wherein God, being minded to show more abundantly unto the heirs of the promise the immutability of his counsel, interposed with an oath;

By faith he became a sojourner in the land of promise, as in a land not his own, dwelling in tents, with Isaac and Jacob, the heirs with him of the same promise:

Hearken, my beloved brethren; did not God choose them that are poor as to the world to be rich in faith, and heirs of the kingdom which he promised to them that love him?
