Abraham was justified (made, or declared righteous) when he believed God's promise for a son coming from his own body. And then Abraham was justified (shown to righteous) by what he did. Both are necessary for salvation.
I totally disagree with your take on the word "justification" in James meaning "shown to be righteous". It obviously means "shown" or proved to MAN, which doesn't make sense because no one was on the mountain with Abraham and Isaac. This is what I meant when I said this view twists the words of Scripture.
I don't want to hijack this thread and turn it into a discussion of James 2. I'll just focus on this one sentence. When Abraham "believed God..." it was in Gen. 15:6, he didn't offer Isaac until Gen. 20. These two things happened years apart. Was Abraham justified when he believed, but not saved until he "showed" it years later? That's not what Paul said.
Concerning Hebrews 11 being about "saving faith"...
I don't know. The passage is talking about faith that pleases God. I had faith that did pleasing things for and because of God, before I actually placed my trust in Christ's blood. But I wasn't declared righteous until I had a very specific faith in God's promise of His Son, Jesus. A Son that would come from my own Body via the Holy Spirit. And that is the point.
First of all, it's not one passage its an entire chapter dedicated to the faith of all the OT saints. This is a treatise that it was FAITH, not works of the law, that saves.
Secondly, this is only about saving faith.
"But as it is, they desire a better country, that is,
a heavenly one. Therefore God is not ashamed to be called their God, for he has prepared for them a city. 17 By faith Abraham, when he was tested, offered up Isaac, and he who had received the promises was ready to offer up his only son, 18 of whom it was said, "Through Isaac shall your descendants be named."
Maybe the word "heavenly" here doesn't really mean "heaven", huh?
I think it is missing the point to go down the road you're going here. Christianity is about faith in the Promised Son of God who would inherit our blessing on our behalf. I don't see value in dissecting every detail of Abraham's life to form doctrine. We know what is important in the account.
I don't know if Abraham was officially justified when he left Haran. It doesn't say. And Hebrews is talking about things that faith did that pleased God--but then again I did things from faith that pleased God before I was actually justified by my faith in the promise of God's Son.
Please. It is you that is missing the point (intentionally?). The point is that in Gen. 12, Abraham had faith and DID WHAT GOD SAID, he left Haran.
"So Abram went,
as the LORD had told him; and Lot went with him."
Isn't this YOUR point concerning James, that the "kind" of faith that saves is the faith that has "works" attached? By your own definition Abraham was justified in Gen. 12, long before he "believed God..." So, my point remains. Abraham was justified more than once, which means justification is an ongoing process, not a one time event.
When you get time, could you please address the following point from my last post, this directly concerns baptism:
So a person must "trust", which is an ACT of the will. If the person doesn't "trust", he is not saved. So, in your opinion, we must DO something or we won't be saved. How is this different from my view on baptism? Having faith, or "trusting" is a work too.
