Most of Israel, God's chosen people, turned away from God, and started worshiping idols, and God blinded their eyes to see the truths of the gospel, until they repent, but they did not lose their eternal inheritance.
God also left in the midst of them an afflicted, and poor people, and they shall trust in the name of the Lord. The remnant of Israel shall do no iniquity, nor speak lies, neither shall a deceitful tongue be found in their mouth, for they shall lie down, and none shall make them afraid.(Zeph 3:11-13).
It is the remnants responsibility to preach, and teach the gospel to the "lost sheep of the house of Israel", praying that they should repent, not to inherit eternal life, which they already have, but to regain their fellowship with God.
Every time that a born again child of God commits a sin, they lose their fellowship with God, temporary, until they repent.
Salvation=deliverance, according to Greek translation.
There is a one time deliverance for those that God gave to Jesus ro redeem them from their sins on the cross, but there are many deliverances for those who have been redeemed as they sojourn here on earth, by their good works, such as; believing, accepting, confessing. and all other good deeds that they do.
