The seed...

The seed of Abraham is not determined by genetics but through faith and obedience through Jesus Christ... For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: [29] But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God. Romans 2:28-29 Not as though the word of God hath taken none effect. For they are not all Israel, which are of Israel: [7] Neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called. [8] That is, They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed. Romans 9:6-8 For ye are all the children of God by faith in Christ Jesus. [27] For as many of you as have been baptized into Christ have put on Christ. [28] There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus. [29] And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise. Galatians 3:26-29 Wherefore also it is contained in the scripture, Behold, I lay in Sion a chief corner stone, elect, precious: and he that believeth on him shall not be confounded. [7] Unto you therefore which believe he is precious: but unto them which be disobedient, the stone which the builders disallowed, the same is made the head of the corner, [8] And a stone of stumbling, and a rock of offence, even to them which stumble at the word, being disobedient: whereunto also they were appointed. [9] But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light: [10] Which in time past were not a people, but are now the people of God: which had not obtained mercy, but now have obtained mercy. 1 Peter 2:6-10 Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ. Galatians 3:16 Jesus saith unto them, Did ye never read in the scriptures, The stone which the builders rejected, the same is become the head of the corner: this is the Lord's doing, and it is marvellous in our eyes? [43] Therefore say I unto you, The kingdom of God shall be taken from you, and given to a nation bringing forth the fruits thereof. [44] And whosoever shall fall on this stone shall be broken: but on whomsoever it shall fall, it will grind him to powder. Matthew 21:42-44
