For the record, I believe people have always been saved by grace through faith. And I believe the same Spirit that indwells us, indwelt them.
It is true to say that OT covenant Israel would have done works because they were also in a covenant of works. And obedience brought blessings and disobedience brought cursing. But the old covenant was meant to show the people their inability to remain faithful and was to point them to Christ. Before they covenant of Sinai, there was already a covenant of grace operating as early as Adam and Eve. We find it extended through Seth, Enoch, and Noah, before it becomes pronounced to Abraham. So there were 2 covenants operating at the same time. The covenant of works was always secondary and designed to preserve Israel and point to the need of something more. That something more was Christ and grace.
The underlying fact is people of the old t did not have a heart that was conditioned enough to receive salvation, well let' say maybe there where some exceptions, excelling in the examination we all face. But for most part God's word was enforced to people of the old t
( The father wills or no will at all to be blunt sir.) obey or be punished, be good receive reward.
That's all that can be done for the unsaved sir.
But maybe just maybe some people realised I can be good because I want to be that way after the father examining there heart.
But then maybe just maybe, some people say I don't need to be told to be good because you say so. I am good, you know what i mean sir.
Apart from perhaps some exceptions who if Jesus would have come earlier perhaps they could have received salvation whilst they lived and breathed, how big that number I do not know, I would like it to be higher that what can be thought of tho
But Jesus never came until he did.
But the same rules still apply for people today sir , all people have the same examination of the heart as people of the old t did, and I would like to believe the examination is easier today than it was then, but I can't see it sir, especially with so many ancient traditions being abandoned, it could be but I suspect for people of the old t committing more seriously offences as they did, they would have had a higher degree of examination. Through God for-knowing every one sir.
Disaplin has changed, these days you can have freedom to do what you want sir.
Nothing has changed in that respect of the examination of the heart all unsaved people have to undergo sir. But the lord said there will be a great falling away
I may add also it makes no difference sir if Jesus had not yet come, in our life time, you me would be waiting in line with the people from the old t, waiting in line to be preached to, if the lord God felt you should be preached to that is after your own personal examination of the heart and earthly death,
But Regardless sir of what I believe, there my beliefs and I'm only sharing them with you, or anyone else reading this.
I would express tho, if they are going to challenged I would prefer to be spoken to appropriately,
its always a good thing to share faith appropriately I feel.
Have a good day sir
