Please understand, we are having a discussion, not an argument. But I don't know how else I can phrase this. Paul wrote in two different places what the faith of Abraham was.

Romans 4
>18 In hope he believed against hope, that he should become the father of many nations; as he had been told, “So shall your descendants be.”

Romans 9
>9 For this is what the promise said, “About this time I will return and Sarah shall have a son.” 10 And not only so, but also when Rebecca had conceived children by one man, our forefather Isaac, 11 though they were not yet born and had done nothing either good or bad, in order that God’s purpose of election might continue, not because of works but because of his call,

Abraham had faith that his offspring would be many great nations. He did not have faith that Jesus would come from his seed.
