I can see salvation as a process in this way.....our final salvation is a process in developing our holiness(theosis) because at any time along the way we can fall from grace and be lost, if we so choose, through lack of faith, which leeds to playing with sin and the severing of the communion with God.
Could there not be a CURRENT state of salvation and then a FINAL salvation?
......and to futher this.....Is the orthodox believer able to say that I am saved NOW, because of what God has done for me through Christ, and will be saved in the end IF I maintain the faith I had in the beginning(and now) unto the end?
