The same people, the elect. God choose them before he formed the earth, and predetermined that his Son would adopt them as his children. When they are born into this world, by natural birth, they are born dead in tranmspasses and sins, in the lusts of their flesh, fulfilling the desires of the flesh and of the mind, and were by nature the children of wrath, even as others, until God quickens them together with Jesus Christ in the new spiritual birth. They cannot believe in the things of the Spirit, until they have been born again spiritually.
Faith can deliver (save) a born again child of God (his elect), while they sojourn here on earth, by them performing good deeds, but our faith is not the cause of getting eternal live. The only thing that eternally saves (delivers) God's elect is by Jesus remitting their sins on the cross, and securing their eternal inheritance.
