Now even continuing in belief is not required? The continuing part is in John 15, where one must abide in Christ or be cut off by the Father.
The same John who wrote they went out from us also wrote about abiding. Yes there are some who depart from the true believers that were never saved as John states, these were the gnostics who denied Jesus had come in the flesh. There are also many who were in the faith, and then departed from the living God, which is completely biblical, not only is the phrase departed from the living God biblical, so is the parable of the sower where some believe for a _while_ but then fall away due to circumstances. So they did indeed believe for a while, so this idea that they never had faith to begin with is just not biblically false, its also demonstrably false and we see people lose faith in many things daily.
You need to explain how some people could have received the Spirit, begun in the Spirit and ended up in the flesh, were severed from Christ and yet this means they are still saved but are just not enjoying the fuzzy feelings of grace. There are so many verses of people departing from the faith and I do not buy into the explanations I have heard so far, they are just too weak and effectively nullify the whole meaning of the passages. Which is exactly my biggest concern with this doctrine, you cannot go to someone and rebuke them, because what is going to happen if they do not repent? Nothing, God will "punish" (reward more like) them by taking them home early if it gets too far. There it is, absolutely nothing will happen. Only thing you can say is you are not sure if that person is even saved, and at which point its back to Calvinism of guessing which one is truly saved and which is not. Where is waldo? theology.
A brother in the Rapture thread pointed out in the beginning of it that he feels internet debates are pointless because people rarely if ever change their view.
I looked back on it and it has been 42 pages and not a single person has conceded on a single point they had. This has caused me to think perhaps the man is right, this is largely meaningless, as we have probably all heard the same arguments a thousand times. I will reply back if some new valid explanation is provided to how some people could have received the Spirit, begun in the Spirit and ended up in the flesh, were severed from Christ and yet this means they are still saved but are just not enjoying the fuzzy feelings of grace or are out of position with grace or whichever argument people have used here. If not I will just let it be, I said what I had to say and I got my mocking blocker on. What joke will stand up comedian mr.military come up with? Something clever and snappy, if only that would answer any of our questions.
EDIT 1: I also would like to say I do not believe there is anyone here who is against OSAS because they don't want it to be true. I am sure me you and everyone would love for OSAS to be true. Smooth sailing, that is what people like, including me.
