What is the difference between eternal security and perseverance of the saints?
Both teach that a true believer will be saved to the end, but they ground it differently. Perseverance of the saints (the Reformed P in TULIP) rests security on unconditional individual election. Eternal security, as this platform holds it, rests it on the sealing of genuine faith in Christ.
What the text states
The outcome is the same: the truly saved are kept. The difference is the anchor. The Reformed view reasons backward from the decree, the elect were chosen individually before time, therefore they cannot fall. This platform reasons from the sealing: the moment a person believes he is sealed with the Spirit "unto the day of redemption" (Eph 1:13, 4:30), and that seal is God's guarantee. The security is just as certain, but it hangs on Christ's finished work received by faith, not on a hidden roster.
The Reformed reply is that without unconditional election, security has no foundation, if a man's faith secured him, his wavering could lose him. We answer that it is not the man's grip but the Spirit's seal that holds, and that the seal is placed at faith and never removed (John 10:28-29).
