When we first believed we experienced SpiritSalvation. As we grow in Grace and knowledge of Jesus Christ we experience a measure of SoulSalvation. Yet, despite our pressing toward the MarkForThePrize we never quite make it in this earthly body.
At the return of Christ, we will be changed from corruptible to incorruptible - the body showing the evident change - but our soul as well will be perfected. The redemption work of Christ in us will be finished on that day.
