'Heirs' in the Bible

For if those who are of the Law are heirs, faith is made void and the promise is nullified;

and if children, heirs also, heirs of God and fellow heirs with Christ, if indeed we suffer with Him so that we may also be glorified with Him.

And if you belong to Christ, then you are Abraham’s descendants, heirs according to promise.

so that being justified by His grace we would be made heirs according to the hope of eternal life.

In the same way God, desiring even more to show to the heirs of the promise the unchangeableness of His purpose, interposed with an oath,

Listen, my beloved brethren: did not God choose the poor of this world to be rich in faith and heirs of the kingdom which He promised to those who love Him?
