What's the point?
MOST believers in today's Western churches are in terrible shape spiritually!
If they do not repent of their habitually-sinning lifestyle, they are NOT going to heaven.
That's the point.
OK, but most believers in all churches everywhere are in "terrible shape spiritually." As my wife (a lifelong resident of the USSR) points out, most Russian Orthodox of her acquaintance (and there have been thousands) know no more about the Bible than do most atheists, and the Russian Orthodox church seamlessly brought more than 1/3 of the formerly atheistic Communist regime into its administrative hierarchy without missing a beat. So don't be under any illusion that genuine spirituality magically begins the moment you leave the borders of Western Christianity.
Have you been deceived into believing in “once saved, always saved”,
and that your sins (past, present, and future) have all been forgiven?
(Also, have you been deceived into believing in a pre-tribulation rapture?)
Heads-up! The dozens of warnings in the NT are there for a purpose!
Statements like this led me to believe that you were not merely issuing a general reminder to all Christians to be more attentive to their Christian walk but had a much more specific doctrinal agenda - i.e., reopening the same old same old OSAS vs. OSNAS debate that has been beaten to death. Am I incorrect? When you state that Kidron that is "in Kindergarden Christianity slurping milk," this sounds to me like someone who is simply looking for a fight (and probably ought to be more concerned about the state of his own spirituality).
My point is that, regardless of whether one is OSAS, OSNAS or some variant, all one can do is prayerfully lead the best Christian life of which one is capable with the guidance of the Holy Spirit. Bible-thumping harangues really serve no purpose. This being a place called Christian Forums, surely you didn't think that most participants here were completely ignorant of the verses you quoted? I and they are fully aware of them. We factor them into our Christian beliefs, whatever those may be. When all is said and done, all we do and all we can do is prayerfully lead the best Christian lives of which we are capable according to our understanding of the Bible and Jesus' message with the guidance of the Holy Spirit.
What you are saying would make sense only if you thought that most Western believers were in terrible shape spiritually
because they accepted the OSAS position. I don't have statistics, but I feel sure that the OSAS position is a minority one in Western Christianity. Moreover, as I have stated, I don't believe and have not seen any evidence to suggest that those who hold the OSAS position lead objectively different (i.e., less God-pleasing) lives than do those who hold the OSNAS position or some variant.
So again I ask, rhetorically, what's the point? Reminding all Christians of the verses you quoted is always worthwhile, but statements like "Have you been deceived into believing in 'once saved, always saved'?" seem to suggest that you are really speaking only to the OSAS community and are under the impression that those in this community lead vastly less God-pleasing lives than do those in the OSNAS community. Everything that I have observed suggests this is a false premise.
