Close but no cigar
"Salvation" rests in the doctrine of justification. Justification is in the aorist tense in Greek and is used to denote a 1-time act wherein the results are seeing throughout eternity ie there is a punctiliar point in time where we as believers are "justified". Justification is the act whereby God looks at the sinner in mercy and says "because of your faith in my Son (the Lord Jesus Christ), I pronounce you justified/forgiven/made right with God".
It is because of "justification" that believers cannot "lose" their salvation-how can we become "unjustified" since Justification results in a pardon of the guilty party. Justifucation is seen in the Bible as a 1-time act.
In the NT, we are told that we are a "new creation in Christ Jesus". The word new (nuos) means totally new with nothing of the old self present ie our hearts are totally new think of the heart of stone has now become a heart of flesh
After justification, the believer is the involved in the process of sanctification which is also referred to as the "christian walk"; it is here that we are come boldy before the throne of grace to receive mercy (Hebrews) and we are to repent of our sins daily that we might walk holy, humbly and in love until death.
Glorification is when we get to heaven and we are made completely new including the body where there will be nothing left of our sinful mortal self.
The above view is very traditional and well within the mainstream of Christian thought. However, in my opinion is is slightly off the mark.
1) Salvation includes justification, and does indeed rest of the finished work of Christ.
2) Salvation is understood to involve three parts,
(1) positional sanctification where God transfers us out of the realm of darkness into the kingdom of His Son. This is a one-time event with continuing effect, those transferred will always (eternally) be "in Christ."
(2) Progressive sanctification where we strive to become more Christ like and serve Christ as ambassadors. It is in this part of salvation where we earn rewards, or not, and this loss is sometimes referred to in scripture as "loss" of salvation. The people who suffer this "loss" still enter heaven but as one escaping from a fire, bringing little or no rewards with them. On the other hand, those that are faithful servants enter heaven "abundantly."
(3) Ultimate sanctification where we are clothed in glorified bodies and meet Christ in the air, our adoption when Christ returns.
3) Justification occurs when the person transferred undergoes the circumcision of Christ where his or her sin burden is removed, thus made holy, blameless and perfect, faultless.
4) You are spot on, we can never loss our "salvation" because we do not have the power to become unjustified, un born anew, un made alive, un made holy and blameless, and so forth with all of these "one time acts" done monergistically by God.
5) When we arise in Christ, we are indeed a new creation created for good works (the reward earning phase of our salvation).
6) As we strive to become more Christ like, this includes confessing our sins, and our renewed effort to return and stay on the path of righteousness. If we say, that we have not sinned, we are not "in Christ" for our indwelt Holy Spirit will bring our short-comings to mind.
7) Glorification spiritually occurred when we arose in Christ a new creation, and will occur physically when we clothed in glorified bodies and Christ's second coming.
