1. They were all FULLY FORGIVEN just as the servant in the parable who was expected to forgive others JUST as HE really had been FULLY FORGIVEN ALL.
Hence eternal security. The righteous stay righteous. And unless the wicked repents, the wicked remain wicked.
Hence your problem with the parable as it teaches "forgiveness revoked" for the FULLY FORGIVEN. you keep highlighting the flaw in your own argument as if I am supposed to "miss it'.
The parable teaches no such doctrine. That is a figment of your imagination. You are forcing it into the parable, but it is not taught elsewhere. Parables do not teach doctrine they illustrate doctrine already taught.
Furthermore, you just demonstrated eternal security. The apostles never lost their salvation. The forgiven stay forgiven.
5. There is no such thing as your highly fictional "when you warn someone of a danger then they automatically reject your warning and are victims of the calamity you were warning them about'. Your argument in that regard is nonsense.
This is the scenario that you are setting up. Jesus, a God of love, is threatening his disciples whom he dies for, with doom and gloom. It doesn't add up does it?
1. The text does not deal with getting salvation back after you lose it -- it just deals with losing it so you "leap to some other subject" like one about "how do you get it back".
Your the one that deals with that. If it deals with forgiveness revoked then you must have an answer for getting it back. How do you get it back Bob? What do you tell your followers? Or do you let them wander hopelessly in to the direction of hell and then just jump off the cliff right into the pit?? Your a sad case if you can't answer that one and not give hope to those who have none.
All you can say is: "the text doesn't teach it."
Your a lost cause without hope.
2. Romans 11 states of those who have lost salvation "He is able to graft them in AGAIN if they do not continue in unbelief". Which answers your question -- but since this is not about "how to get it back" not sure why you want to jump over to that other subject.
The subject is in the parable. The parable is about forgiveness. You read into the parable forgiveness revoked, which I contend is not taught. If you believe it is taught then you must take it one step further and teach how forgiveness is regained. Romans 11--a passage directed to Israel--doesn't help you here.
3. The actual BIBLE says "IF we CONFESS our sins He is faithful and just to FORGIVE us our sins". It does not have your "forgiven when you do not confess your sins" doctrine. So not sure why you are "quoting you" to come up with such a doctrine.
Now we are back to eternal security.
This verse is written only to believers. Notice the "we" which includes "John," who never lost his salvation, and was never in danger of hell. (Although your teaching put him there with the teaching and conclusions drawn from Matthew 18 and also Matthew 6).
1John 1:9 is exclusively written to Christians who are sure of their salvation. They confess their sins to keep in fellowship with God, not because they have any fear of losing their salvation. The are eternally secure in the hand of God.
So now --- back to the questions that actually deal with the subjects that come up in Matt 18 and Matt 6 on forgiveness revoked for those FULLY FORGIVEN.
1. There is no such doctrine as forgiveness revoked and no passage in scripture that teaches it. Certainly, not the passages that you have misinterpreted.
2. If anything, you demonstrated how they teach eternal security instead.
3. Not one of the apostles lost their salvation. Their sins had been forgiven: past, present and future. Their names are all written on the foundations of the walls of the New Jerusalem. Obviously, these passages that were addressed to the apostles, were not about THEIR forgiveness being revoked.
4. It is clearly evident that you ignore the context of these passages.
5. Now it is your turn to come back and tell me that I have not addressed your question in the text. I have, just not given you the answers you want to see. You need to address the points I just put forward.
