No one is ever saved by works or faith+works in the OT, NT or end times. I agree with Walvoord, the works mentioned are the fruits of salvation by God’s Grace effecting regeneration of the believer.
There is only one Gospel and it was preached by all the apostles (1 Corinthians 15). There are no other gospels out there.
Where we sometimes get wrapped around these passages of “the righteous” or “those doing good” entering the Kingdom is because we don’t read Paul’s epistles fully. He spends a good amount of time telling us that those saved by Grace are conformed to the Image of the Son. That is only possible by Christ abiding in us and we in Him. This means doing what Christ told us to do. We do so because He paid for us with such a price.
Our earthly fathers do not measure their love for us in the chores we do for them. They are, however, well pleased at our love back, our earnest work showing them we believe their example and strive to imitate it. That is faith in action not works.
For if at some point the Gospel changes then that means it is no longer Grace but works.
Sorry for the length but even gentlemen like Walvoord warned us of the hyper dispensationalism even in his time. The type which asserts Peter et al. preached a different Gospel than Paul. One Gospel, One Body of Christ.
You and I obviously disagree...I can live with that...
The Apostle James writes that we are justified by works and faith together. The Apostle Paul writes we are saved by grace through faith. Since the scripture cannot be broken, both must be equally true. We are being saved by grace through faith in concert with works of faith that produce fruit of righteousness, and it is the gift of God. Seest thou how faith wrought with his works, and by works was faith made perfect? 23 And the scripture was fulfilled which saith, Abraham believed God, and it was imputed unto him for righteousness: and he was called the Friend of God. 24 Ye see then how that by works a man is justified, and not by faith only. For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: 9 Not of works, lest any man should boast.
