On the surface, calvinism seems the opposite of the Arminianism persuasion. But they are pretty much the same.
Calvinism just says that you were not "really" saved if those points are true in the end Of a persons life.
Perseverance of the saints is EXACTLY the same as loss of salvation if one really studies it out.
1 Just says that you were really saved and lost it.
The other just says you were not really saved and lost the salvation that you "thought" you had.
But eternal security is preservation of the believer.......because salvation depends upon the character and nature of the Lord Jesus Christ. Not the character and nature of the believer.
Rewards, reign, rank and ETERNAL blessings, may be lost based upon the behavior of the believer. They may have shame at the judgement seat of Christ. And not be presented holy and blameless and be saved as if through fire to refine them..........but they are saved.
After salvation, we are working for His Glory. And if we Glorify him little, we will be a "private." if we glorify Him much we will be a "general"(lords and kings in His Kingdom.) So there is much at stake, just not our eternal life.
There are many people who are saved and lose faith. the pressures of the world drag them down or a sneaky snake comes along and steals their joy with RELIGION.
2 Tim 2~~
11It is a trustworthy statement:
For if (and we have/first class condition)we died with Him, we(His Body) will also live with Him;
12If we endure, we will also reign with Him;
If we deny Him, He also will deny us(that reign);
13If we are faithless, He remains faithful,
for He cannot deny Himself.
Eph 5~~29for no one ever hated his own flesh, but nourishes and cherishes it, just as Christ also
does the church,
30 because we are members of His body.
