The seed are the children/offspring God gave Christ to die for Isa 53:10The seed mention refers to Christ, who God will see as his seed. I don't even see believers in the picture. I see no mention of converts or any conversion. You have to twist a lot to make this verse fit your theory. Which is why it is so easily seen as a theory because none of the text you use corroborates your view. I think you assume that the word "seed" which is a metaphor, has the same meaning in every context. This context has no believers even being referenced.
once again You are confused. Seed here does not mean believers. You bypass the whole context by dwelling on the word "seed" not even knowing to whom it is representing.
First, start with vs 13. God's promise that Abraham would be heir to the world was not to Abraham through the law but through faith.
Then it says if those who are of the law are heirs, faith is made void and the promise of no effect.
vs 16 Paul is stating it is of faith that it might be according to grace, so that the promise might be sure to all the seed, not only to those of the law, but to those who are of the faith of Abraham, who is the father of us all. Meaning, Abraham offspring are spiritual, he is the father of all who believe, Jew and Gentile vs16-17.
The word "seed" refers to Christ. When the word descendants is used in vs 18 he is speaking of the descendants of Abraham's faith.
Check Gal 3:16 for the descendant of Abraham - it is not believers
These texts do not support your view. Why do you choose them? Is it because you don't understand them or you need the word "seed" and twist the meaning out of context?
There is that word again, "seed". Two translations use seed, others use the word posterity. Either fits because it refers to believers who will tell others for generations.
Isn't it the norm for believers to serve God and to spread His Gospel. Believers worship Him, supposed to anyway. Nothing here again to support your view that Christ made converts/believers from the Cross. Nothing in the whole chapter explains or mentions how one becomes a believer. They are just assumed to exist.
10 Yet it pleased the Lord to bruise him; he hath put him to grief: when thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the Lord shall prosper in his hand.
The children Heb 2:14
14 Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil;
