The Bible speaks of the fact that, few will make it (narrow is the way, remember?)
Are you saying that all godly Christians who reject OSAS are not saved?! despite not rejecting Christ/gospel (which does not talk about POTS)?
Every cult (JWs, Mormons, etc.) also use this verse to argue that they must be right because they are the minority. The verse shows that Jesus is the narrow way (vs Buddha, Mohammed, New Age, Rev. Moon, JW, Mormon), not how many or few will end up in the kingdom (there are more Christians than any other religion, but more unbelievers overall). Most Christians are not OSAS.
Don't make a doctrinal dispute tantamount to the gospel (like hyper-Calvinists claiming one must accept TULIP or their view of sovereignty or you have a false god/gospel).
Are you related to serpentdove? You have the same spirit/ad hominem propensity she does.
