n2thelight gave a very good exposition on that involving Isaac, and I have mentioned the Promise by Faith to Abraham being passed to Isaac and his seed with that Promise being about The Gospel of Jesus Christ.
Gal 3:22
22 But the scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe.
KJV
Gal 3:29
29 And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise.
KJV
That applies equally to all... believers on Jesus Christ, regardless of birth.
No he didn't. He is out to lunch as you are. Don't rely on others else you will find you will have to defend all that they say. You have no answer and continue to ignore the example of election following Paul's statement that the children of promise are counted for the seed. This shows that the children of promise are of promise before they are born.
And all believers follow that pattern as Paul said in (Gal. 4:28) "Now we brethren, as Isaac was, are the children of promise." This is contrary to what intothelight said, as he said in Isaac is the seed called then all others are called in Christ. Paul says we are as Isaac was, children of promise.
And nothing is told us here of Isaac having any faith to be a child of promise. The promise came before he was born. And we, as Isaac was, are children of promise.
