I feel like this is a case of tomato tomaato...and too vague to reply to. Best reply is from an OO perspective:
We believe that we were gripped by death and sin. The life-giving God took flesh, became man, abolished the power of death, and gave us His very own divine life by living inside us, leading us away from sin to a direction towards God. Thus, in baptism, we receive the Holy Spirit and in chrismation we are made "Christs", anointed to be children of the Father. We also continually partake of the life-giving body and blood of Christ to be waxed into His flesh as the Body of Christ, in an intimate and most amazing union. We are then to take this source of our salvation, the God who lives inside us fully, to go out and blessed the world, season it with the salt of Christ, and enlighten it with the light of the divine nature. Our wills are to conform to the will of God through Christ by the Holy Spirit. Day by day, we perform works that are filled with the fruit of the faith that we have of Christ who continually resides in us and becomes a part of us as we become a part of Him, not just physically and spiritually, but also in our actions towards ourselves and others. Our justification IS our sanctification. In the waters of baptism, we are made holy because we have the SOURCE of ALL HOLINESS residing in us and permeating through ever fiber our being. And we continually grow in our holiness as we glorify the Holy Trinity who continually glorifies us as they dwell in us and we partake of the Holy Glory of the Divinity.
Christ is one nature, one will, and one energy that we may also be one with the Father, Son, and Holy Spirit, one with Christ, one in Sonship with God the Word to the Father, by the Holy Spirit. One in will and energy. One in our lives. As the Father and Son are one, we also are made one with them. Oneness is justification, sanctification, and glorification. Oneness in faith leads to oneness with the will of God in our works.
Wo are us who have in us God living, and yet we live not according to His will. Wo that our oneness becomes false by our lack of works. Wo that we partake of the Eucharist in an unworthy manner, where we do not live a life of continued repentance, but of negligence. For if St. Paul teaches it is possible to eat and drink condemnation, we also fall into condemnation if we do not heed to the will of the divine Lover of Mankind who lives in us and One with us. Wo that our oneness splits into two separate realities like the demons, who profess correct faith in God, and yet do not do the works that are worthy of the faith of God, as St. James teaches.
