Thanks for all that.
I believe that there is a difference in being granted salvation between the OT and the NT.
In the OT, where men couldn't be free from sin, they had the Law's measures to deal with their sins.
In the NT, by the grace of God, rebirth, and the gift of the Holy Ghost, we have no need of those measures; as we can remain faithfully true all the time.
Okay, I wanted to make sure because it sounded like that was your stance. So essentially, you're a dispensationalist when it comes to salvation and Cameron is arguing against it. He's saying salvation has been the same throughout history. I actually agree with Cameron.
In Ezekiel 40-48, it shows that sacrificial offerings (the word sacrifices that people use) return during the millennial reign and that includes sin offerings. Paul also continued to sacrifice after his conversion as in Acts he had to give a sin offering at the end of his Nazarite vow which is required and he even paid for other men for their sin sacrifices to prove to the Jews he wasn't stepping away from the law (Acts 21).
So the whole sacrificial system is widely misunderstood and since it never did away with sin (as per Hebrews), we can't use it as an argument that says salvation somehow changed from before Christ to after Christ.
Here are some examples of Old Testament people saying God forgave them of their sins by grace:
David-
I acknowledged my sin to You,
And my iniquity I have not hidden.
I said, “I will confess my transgressions to the Lord,”
And You forgave the iniquity of my sin.
Selah - Psalm 32:5
Moses-
And the Lord passed before him and proclaimed, “The Lord, the Lord God, merciful and gracious, longsuffering, and abounding in goodness and truth, keeping mercy for thousands, forgiving iniquity and transgression and sin, by no means clearing
the guilty, visiting the iniquity of the fathers upon the children and the children’s children to the third and the fourth generation.” - Exodus 34: 6-7
Nehemiah-
They refused to obey,
And they were not mindful of Your wonders
That You did among them.
But they hardened their necks,
And in their rebellion
They appointed a leader
To return to their bondage.
But You
are God,
Ready to pardon,
Gracious and merciful,
Slow to anger,
Abundant in kindness,
And did not forsake them. - Nehemiah 9:17
Micah-
Who
is a God like You,
Pardoning iniquity
And passing over the transgression of the remnant of His heritage?
He does not retain His anger forever,
Because He delights
in mercy.
He will again have compassion on us,
And will subdue our iniquities. - Micah 9:18-19
Salvation was always the same from the beginning. Choosing God, following Him, walking in His obedience and obtaining mercy and grace. Sacrificial offerings were a means to draw closer to God, not for salvation. It actually has nothing to do with salvation, which is why it doesn't surprise me that they return during the millennium.
