What About The Land God Promised To Abraham?

St. Irenaeus, Against Heresies, Book 5, Chap. 32, AD 180: “Thus, then, the promise of God, which He gave to Abraham, remains steadfast. For thus He said: Lift up your eyes, and look from this place where now you are, towards the north and south, and east and west. For all the earth which you see I will give to you and to your seed, even forever [Genesis 13:13-14]. And again He says, Arise, and go through the length and breadth of the land, since I will give it unto you [Genesis 13:17]; and [yet] he did not receive an inheritance in it, not even a footstep, but was always a stranger and a pilgrim therein [Acts 7:5; Hebrews 11:13]… Thus did he await patiently the promise of God, and was unwilling to appear to receive from men, what God had promised to give him, when He said again to him as follows: I will give this land to your seed, from the river of Egypt even unto the great river Euphrates [Genesis 15:13]. If, then, God promised him the inheritance of the land, yet he did not receive it during all the time of his sojourn there, it must be, that together with his seed, that is, those who fear God and believe in Him, he shall receive it at the resurrection of the just. For his seed is the Church, which receives the adoption to God through the Lord… Thus also the apostle says in the Epistle to the Galatians: But you, brethren, as Isaac was, are the children of the promise [Galatians 4:28]. And again, in the same Epistle, he plainly declares that they who have believed in Christ do receive Christ, the promise to Abraham thus saying, The promises were spoken to Abraham, and to his seed. Now He does not say, And of seeds, as if [He spoke] of many, but as of one, And to your seed, which is Christ [Galatians 3:16]. And again, confirming his former words, he says, Even as Abraham believed God, and it was accounted to him for righteousness. Know therefore, that they who are of faith are the children of Abraham. But the Scripture, foreseeing that God would justify the heathen through faith, declared to Abraham beforehand, That in you shall all nations be blessed. So then they who are of faith shall be blessed with faithful Abraham [Galatians 3:6], etc. Thus, then, they who are of faith shall be blessed with faithful Abraham, and these are the children of Abraham. Now God promised the earth to Abraham and his seed; yet neither Abraham nor his seed, that is, those who are justified by faith, do now receive any inheritance in it; but they shall receive it at the resurrection of the just. For God is true and faithful; and on this account He said, Blessed are the meek, for they shall inherit the earth [Matthew 5:5].”
