I think the "goal" of theosis is union with God. To say it is salvation is more of a protestant way of looking at it. The goal of life, for the most common, illeiterate peasant attending divine liturgy and saying some prayers learned at their mother's knee, or for the most extreme ascetic, or for a dad with a job and kids, who likes to take a nice vacation and other typcally American middle class lifestyle perks is equally to have union with God. We experience that most of all in the Eucharist in this life. Any spiritual disciplines we can add, like a rule of prayer, fasting, giving alms, help us.
Theosis is a process. We are all on the path to deification. If we are baptized & chrismated, avail ourselves of confession and liturgy and the eucharist we will hopefully enter the eternal kingdom and we will be changed into his likeness. How much of that change we realize in this life is in our hands to work out our salvation with fear and trembling. Also, the more we realize in this life the greater will be our joy and partaking of the divine nature in the next.
The blessing for us in being able to witness and recognize deification in the lives of the saints is that it sets a goal and example for us to strive for, as well as hope. ÃƒÆ’Ã¢â‚¬Å¡ At one point they were each like us. Who knows where we will be on the ladder of divine ascent a year from or now or ten years from now.
My whole point being that theosis is a dynamic process, not a static state, possible for all Orthodox Christians.
