'Heritage' in the Bible

Because if the heritage is by the law, it is no longer dependent on the word of God; but God gave it to Abraham by his word.

And if you are Christ's, then you are Abraham's seed, and yours is the heritage by the right of God's undertaking given to Abraham.

So that you are no longer a servant, but a son; and if a son, then the heritage of God is yours.

What then do the Writings say? Send away the servant-woman and her son; for the son of the servant-woman will not have a part in the heritage with the son of the free woman.
