Fairly harsh position for you to take.
Context:
7:1 "Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh..."
--Dearly beloved refers only to believers.
--"Let us" Paul includes himself.
2Co 7:2 "Receive us;..."
--He is writing to the church at Corinth which he himself defined as "saints." He wants them to receive Paul and his company when they come. Hardly the hospitality becoming of unbelievers.
7:3 "...ye are in our hearts to die and live with you."
--Paul stood against the doctrine of the ungodly. He was willing to die and live with the believers.
2Co 7:4 Great is my boldness of speech toward you, great is my glorying of you: I am filled with comfort, I am exceeding joyful in all our tribulation.
--A statement like this could only be written to believers.
He was bold toward them because his previous letter contained rebuke.
They had repented, which filled Paul with both comfort and joy.
In the conditions of that day they were both going through tribulation, and in context the trial of the problem was as a tribulation as well.
2Co 7:5 For, when we were come into Macedonia, our flesh had no rest, but we were troubled on every side; without were fightings, within were fears.
--Paul shares more of his tribulations with the saints at Corinth.
2Co 7:6 Nevertheless God, that comforteth those that are cast down, comforted us by the coming of Titus;
--The church at Corinth had sent Titus with a message. When Titus finally arrived, he was comforted by the coming of Titus.
2Co 7:7 And not by his coming only, but by the consolation wherewith he was comforted in you, when he told us your earnest desire, your mourning, your
--Titus had informed him of the situation in Corinth--their desire to be right with God; the comfort that Titus himself was able to give to the Corinthians, and their consequent mourning of the sin that they had committed and now had repented of.
2Co 7:8 For though I made you sorry with a letter, I do not repent, though I did repent: for I perceive that the same epistle hath made you sorry, though it were but for a season.
Paul had written them about a specific sin. Titus had come to deal with that specific sin. They had repented over a specific sin. Paul was not sorry for writing a fairly harsh letter to them that they needed to repent over this specific sin. It had nothing to do with salvation. If they did not repent their fellowship with God would remain broken. They would not lose their salvation however.
His epistle made the sorry, but it was for a short time.
2Co 7:9 Now I rejoice, not that ye were made sorry, but that ye sorrowed to repentance: for ye were made sorry after a godly manner, that ye might receive damage by us in nothing.
--They were sorry for that one sin that they had committed. It was true and genuine sorrow. As a church they repented. They were united in this. This was a Godly thing or step that they made in order to move forward.
2Co 7:10 For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death.
--Because they sorrowed or grieved over the sin committed, it led to a "change of mind and life" that they would not regret again. The word "salvation" is an unfortunate translation. It simply means "a change of mind." That is what they had concerning this sin--a change of mind.
--It is the sorrow of the world that ends in death.
Does that make things clear?
An unsaved man cannot have "godly sorrow" for there is no godliness in him for which he is able to have "godly sorrow."
