No offense, Scott. I am posting this on the basis of my understanding of what you think your salvation is - which is recent. As for God's people from before the foundation of the world, let Moses speak:
From Psalms 90:1-2
LORD, thou hast been our dwelling place in all generations;
Before the mountains were brought forth, or ever thou hadst formed the earth and the world, even from everlasting to everlasting, thou art God.
When he formed the earth and the worlds, he has always been the dwelling place of his people.
Allelujah to the Living God.
