That has to do with our walk not our salvation.
Our walk (growth) is for the purpose of gloryfying God in time and we get crowns for them (1Cor.3:13-16, 1Cor.9, 1Tim.2, Jam.1:12, Phil.4:1 1Pet.5, Rev.3,)
You are confusing positional sanctification with progressive sanctification.
The race being run has to do with rewards not salvation. (1Cor.9:24-26) What is the one reward that Paul preaches about? Gold? material wealth? power? Of course not, His only mission was to spread the good news of salvation, that is the only reward that matters. Also, if we read a bit further in to Paul's letter, we see that he writes in verse 27 of the same book and chapter: "No, I drive my body and train it, for fear that , after having preached ot others, I myself should be disqualified".
Disqualified from what?
From not getting the rewards he talks about in 1Cor.3-13-16, and the crowns he writes about in 1Cor.9, 2Tim.2 (before his death), Phil.4:1 etc.
The final glorification has to do with our receiving our resurrection Body, not salvation (Rom.8). We don't hope for what is assured, do we.
We don't hope for we don't see but if we hope for what we see not, then we with patience wait for it (Rom.8:23-25)
These things have I written unto you that believe on the name of the Son of God, that ye may know that ye have eternal life (1Jn.5:13) Belief surpasses mere intellectual ascent, the belief that John writes is dynamic, transcendent and not easy to attain, many are called, few are chosen.
The belief that John writes about is for all men who have received Christ as their personal saviour and they should have the assurance that the are indeed new creatures in Christ (2Cor.5:17), born again (Jn.3:3) and therefore, heaven bound (Rom.8:29, 38-39)
Please explain what you think the "crown" is?
