Are you claiming salvation is a merit system taught by James?
Are you a two gospels dispensationalist?
No. I don't believe salvation is a merit system other than the meritorious work of Jesus Christ to secure Eternal Life for those who believe upon Him.
I don't believe what James wrote can fully be reconciled against what other Scriptures declare faith to be. I stopped trying to "read such into" James's narrative a very long time ago.
I don't require a "Abraham offering his only son" moment in any person's life as proof or a requirement of faith.
To whom much is given, much is required. Requirements vary. Abraham literally lived the Gospel in his own immediate family. Which is somewhat of a unique circumstance in the history of faith.
The women I referenced from Matthew 15 and the centurion of Luke 7 did nothing more than confess the obvious realizing they couldn't help themselves.
Mat 15:26 But he answered and said, It is not meet to take the children's bread, and to cast it to dogs.
Mat 15:27 And she said, Truth, Lord: yet the dogs eat of the crumbs which fall from their masters' table.
Mat 15:28 Then Jesus answered and said unto her, O woman, great is thy faith: be it unto thee even as thou wilt. And her daughter was made whole from that very hour.
Luk 7:8 For I also am a man set under authority, having under me soldiers, and I say unto one, Go, and he goeth; and to another, Come, and he cometh; and to my servant, Do this, and he doeth it.
Luk 7:9 When Jesus heard these things, he marvelled at him, and turned him about, and said unto the people that followed him, I say unto you, I have not found so great faith, no, not in Israel.
There are also many works undertaken by men that never actually come forth from faith. They are either never done in faith or they are falsely undertaken for the wrong reasons.
Whatever we do must be in faith "as unto the Lord".
Col 3:23 Whatever you do, work heartily, as for the Lord and not for men,
Rom 14:23 And he that doubteth is damned if he eat, because he eateth not of faith: for whatsoever is not of faith is sin.
Thusly, I don't fit within either of these systems. I feel no need nor see any requirement to do such.
I've "sat back" in my life and watched as so many people try to make the arguments being made here.... and that never actually go anywhere. It is just a vicious circle of debate and one huge false dichotomy. I reject both perspectives.
Abraham wasn't trying to prove himself to anyone in what he did for God. He wasn't trying to express his faith so others might follow him. He simply...literally... lived the Gospel because he believed what God told him.
Everything starts with such simple faith. It has no merit. It gains nothing of itself. It relies solely upon another. God.
