You sin= loss of salvation. You repent= get back your salvation. And so forth on and on.
i understand from your words that if you sin just prior to death, having not repented again that you will go to hell, am I correct?
This discussion has become tiresome.
Matthew 5:
22“But I say to you that everyone who is angry with his brother shall be guilty before the court; and whoever says to his brother, ‘You good-for-nothing,’ shall be guilty before the supreme court; and whoever says, ‘You fool,’ shall be guilty
enough to go into the fiery hell
If I murder, or even hate a brother, without repentance, prior to death without repenting then yes, I would go to hell.
This isn't what some think of as works-salvation, since it's God who decides on whether he wants to grant us repentance, and mercy.
Romans 9:
15For He says to Moses: “I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.” 16So then, it does not depend on man’s desire or effort, but on God’s mercy. 17For the Scripture says to Pharaoh: “I raised you up for this very purpose, that I might display My power in you, and that My name might be proclaimed in all the earth.” 18Therefore God has mercy on whom He wants to have mercy, and He hardens whom He wants to harden.
I also want to add, it's not ideal to live in a constant pattern of sinning followed by repentance, for the same specific sins, over and over again through out the life of a christian. What's preferred is one time of repentance, followed by never going back to a certain sin. For example, if a man is an adulterer, he may repent, but what if he keeps going back to the other woman? What does that say about him, and how long would God tolerate that? God knows.
You didn't ask me but, if I may...I doubt that is necessarily the case, at least with a single slip up. On the other hand, if one chooses to life a lifestyle of general or a particular sin, and is doing that when they die or the lord returns, that is very likely a different story. We need to stop those things, get forgiveness and get back on the right path.
Then there is the "who really knows" side of that. Take the man/woman that was a saint most of their life and just happens to have a weak time in their life just before their demise and doesn't get back to God in time. Not something I would chance with the expectation I'd get away with it but with a fair and just God, who's to say he won't make that or other acceptations, all depending on circumstance.
Best to take no chances, and watch therefore.....
I don't think we have to worry too much when it comes to one slip up. Perhaps I'm wrong, and this is just what I feel is true. It seems that God would have mercy on such a person, and grant them time to repent and continue to live righteously before they die. I don't think he would let the saints who've been practicing righteous living for decades commit an act of adultery out of the blue prior to death. So either I'd say that the scenario you described wouldn't happen, or God would not forgive such a person. What comes to mind is the account of Ananias and Sapphira. God basically killed them right after they lied. I don't feel confident in saying they went to heaven. However, one could also argue they were false-brethren, not really saved to begin with.
What surprises me is Matthew 5:22, which I quoted above. It describes that calling a brother a fool, perhaps out of hate, will put us in danger of hellfire. I think that's an accurate way to rephrase, "loss of salvation", because it doesn't seem quite right to say anyone has lost their salvation because salvation isn't an object, it's an act or process.
So to better address Grafted In, sin=being put in danger of hellfire, and repentance=being secured in Christ.
Taking that into consideration, it seems like we're expected to try to live without sinning from the time we repent. If sin is such a danger, something to be avoided, something that God himself wants us to stay away from, surely we would be able to do so, and live without sin.
