I John 1:8 If we claim to be without sin, we deceive ourselves and the truth is not in us. 9 If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. 10 If we claim we have not sinned, we make him out to be a liar and his word is not in us.
You asked two questions. In your second question, which is tied to your first question, you assume that I believe that repentance means you can never stumble into sin ever again. I have already admitted that believers can occasionally sin without them intending to do so. However, this is a far cry from saying that godly sorrow does not lead to repentance. It does. Otherwise you simply do not believe the Scriptures.
Let me give you an example. If a drunk joins a drug program to be free of his addiction to alcohol, he can stumble on his road to recovery but his stumbling on occasion does not define his end goal of overcoming his addiction in time. His eventual overcoming his sin is repentance of the sin of drunkenness. Oh, and there are lots of people who are alcohol free today and they once were horribly addicted to booze, etcetera. So one can overcome sin.
As for 1 John 1:8:
What is helpful in understanding 1 John 1:8 is looking at its immediate context. 1 John 1:10 says if we say we have not sinned. 1 John 1:10 switches gears from 1 John 1:8 in regards to time; John talks about the declaration on committing sin in verse 8 (which is present tense) to a declaration on committing sin being a past declaration (with verse 10). Verse 10 is saying there are people who said they have not sinned (past tense). This is clearly a gnostic belief. Why? Well, most believers today hold to the idea that they have sinned as a part of their old life before coming to Christ (Regardless of whether they are “OSAS,” a “Sin and still be saved” type believer, or a “Conditional Salvationist”). So this clearly is a “gnostic belief” that John was warning the brethren about (See 1 John 2:26). 1 John 1:8 is a present declaration of sin. It is saying if we say we have no sin when we do sin (present tense). This has to be the interpretative understanding of this verse because 1 John 2:4 says if we say we know Him and do not keep His commandments we are a liar and the truth is not in us. The OSAS's interpretation on 1 John 1:8 does not work because it conflicts with a normal reading on 1 John 2:3-4. You cannot always be in sin (breaking God's commands) as a part of 1 John 1:8 and yet also fulfill 1 John 2:3 that says we can have an assurance of knowing Him if we keep His commandments. Especially when 1 John 2:4 says we are a liar and the truth is not in us if we break his commandments. In other words, if the OSAS interpretation on 1 John 1:8 was true, then I would be damned if I do by obeying God's commands (1 John 1:8) and yet I would be damned if I don't by not obeying God's commands (1 John 2:4).
In fact, the New English Translation says this for 1 John 1:8,
"If we say we do not bear the guilt of sin, we are deceiving ourselves and the truth is not in us." (1 John 1:8 NET).
In other words, this verse is saying that if a person sins and says they do not bear the guilt of sin (in the sense that they will not have to face any wrath or Judgment from God over their sin) then they would be deceiving themselves and the truth would not be in them. This is exactly what the Eternal Security proposes. They are saying that they do not bear the guilt of any sin (destruction of their soul and body in hell fire) if they do sin because they believe their future sins are paid for by Jesus. They are saying, they do not bear the guilt or the punishment of sin at the final Judgment because of their belief on Jesus. In short, 1 John 1:8 is a denial of the existence of sin on some level. “If we say we have no sin (in the sense that it does not exist) we deceive ourselves and the truth is not in us.” (1 John 1:8). Christian Scientists think sin is an illusion and does not exist at all. So this verse would apply to them. Eternal Security Proponents and those who deny that “Sin Can Separate a Believer from God” deny the existence of sin partially. They believe sin exists physically but they do not believe sin exists for them on a spiritual level because Jesus has forgiven them of all their sin by their belief on Jesus. In fact, to see just how silly your argument actually is for 1 John 1:8, you would have to believe that you are sinning right now at this very moment in order for such a verse to be true because 1 John 1:8 is speaking in the present tense.
John prescribes that we do not think that sin is an illusion, and we are automatically saved, but John is telling us to "sin not" and go to our advocate Jesus Christ (1 John 2:1), and confess our sins so as to be forgiven of sin and to be cleansed of all unrighteousness (1 John 1:9). How can you confess and be forgiven of sin if all your future sin is paid for? It makes no sense.
You can say that John is talking about a break of fellowship by one's sins and not a loss of salvation, but that would not be consistent with Scripture. 1 John 5:12 says he that has the Son has life, and he that does not have the Son does not have life.
Many today believe they can sin and God does not see their sin or wickedness because Jesus paid for their sins already (according to them).
However, the Bible does not agree with them.
Proverbs 30:20 says:
“Such is the way of an adulterous woman; she eateth, and wipeth her mouth, and saith, I have done no wickedness.”
Malachi 2:17 AMP
“You have wearied the LORD with your words. But you say, “In what way have we wearied Him?” In that you say, “Everyone who does evil is good in the sight of the LORD, and He delights in them,” or [by asking], “Where is the God of justice?”
Jeremiah 23:21-23
“I have not sent these prophets, yet they ran: I have not spoken to them, yet they prophesied. But if they had stood in my counsel, and had caused my people to hear my words, then they should have turned them from their evil way, and from the evil of their doings. Am I a God at hand, saith the LORD, and not a God afar off?”
Jude 1:4 NIV
“For certain individuals whose condemnation was written about b long ago have secretly slipped in among you. They are ungodly people, who pervert the grace of our God into a license for immorality and deny Jesus Christ our only Sovereign and Lord.”
Titus 1:16
“They profess that they know God, but by their works they deny him, being abominable, disobedient, and unfit for any good work.”
