Brother, I realize you were speaking to Kroogz, and I don't speak for him, but the so-called OSAS, as you call it, is rooted in the scriptural reality of being sealed by Holy Spirit, which scripture never shows as ever being withdrawn, especially given that the EARNEST of Holy Spirit given would entail the Lord forfeiting His own Spirit to withdraw salvation from anyone, it would make Christ out to be unfaithful and denying Himself. If those who believe in loss of salvation want to shake their finger of accusation at Christ for those things, which is what they are doing to say that one can lose his salvation, they will do so without my standing beside them in support.
Additionally, the false claim that OSAS entails living any ol' way one chooses, they need to keep in mind that the only alternative to OSAS is one boasting in their works of effort for retention and, yes, even earning, their salvation. If one can boast of allegedly retaining their salvation through personal effort in doing good works and/or abstaining from various sins, they're boasting no matter how one may try to wriggle out from under that charge.
