You are joking right?
One lustful glance, one moment of unrighteous anger, one millisecond of a dirty thought, one illegal download, a white lie, irritation, even breaking a trivial road traffic law(Romans 13 1-2). is a SIN.
Well, if you don't believe the Scriptures I shown you, let me use a real world example to help you to relate to what I am trying to tell you. Why? Well, because Jesus used real world examples (i.e. parables). Alright, what you are basically saying is that it is okay to slip up into sin every now and then and that you will forever be a slave to your sin.
In other words, when an alcoholic who is honestly struggling to stop in their addiction to alcohol, they are far better in doing the right thing versus say the alcoholic who could care less about stopping (or who thinks it is impossible to stop). So yes; Believers can indeed stop sinning those types of sins that lead unto death, such as hating, lying, lusting, and in getting drunk, etc. For it would be like telling an alcoholic that they will forever be engulfed in their addiction or that they can drink every once and a while. But lets look at the different options side by side.
Option #1. A person is Alcohol free or Sober
Option #2. A person has slipped up on occasion in their honest struggle to stop on their road to recovery (From Alcoholism).
Option #3. A person who is Alcoholic believes they can not be an Alcoholic and yet still drink every once and a while on their road to recovery.
Option #4. A person who is Alcoholic believes they will forever be an alcoholic and yet their choice to not habitually drink makes them okay.
The first two options are Biblical and the last two options are not. For the believer who thinks they can habitually sin and still be saved is essentially saying you are a slave to your sin. Yet, Romans 8 says we are free from the Law of sin and death. In other words, sin will not have rule or dominion in a believer's life because Jesus lives in their heart and life. For the Scriptures say that Jesus Christ was manifested to destroy the works of the devil.
Anyways, your beginning words in your response to me here totally reminds me of the disciples' reaction to the words of Jesus along with His reply back to them in Matthew 19.
"And again I say unto you, It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God.
When his disciples heard it, they were exceedingly amazed, saying, Who then can be saved? But Jesus beheld them, and said unto them, With men this is impossible; but with God all things are possible." (Matthew 19:24-26).
Did you catch that? The disciples were shocked that a rich man could not enter into Heaven and they were thinking who then can be saved? Meaning, this sure is a tough road to salvation. Who can do it? Jesus response was with man this is impossible, but with God.... all things are possible. What does that mean?
Well, let's take a look at Ezekiel 36:26-27.
It says,
"A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh. And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them."
Did you see ? Here in this passage it is saying God will give a person a new heart and a new spirit and then God will place His Spirit within them and cause them to walk within His statutes (laws). So when a person repents of their sins for real and accepts Jesus, they are born again spiritually and they then have the power by the Spirit (working in them) to keep God's good ways (and or to stop sinning).
As for Romans 13:1-2 in regards to a breaking the traffic laws: Well, yes. Breaking the Traffic Laws would be a sin indeed. But doing so would not be a sin that leads unto death, though. For John speaks of sins that lead unto death and sins that do not lead unto death (See 1 John 5:16-18). In fact, the Bible describes three different types of sins.
1. Sins that can never be forgiven.
(Like speaking bad against the Holy Ghost, committing suicide, and apostacy - i.e. rejecting Jesus).
2. Sins that lead unto death.
(i.e. These are the type of sins that Paul lists in the New Testament several times that will cause a person to not inherit the Kingdom of God like lying, adultery, murder, hate, stealing, idolatry, and drunkenness, etc.). (Why are they called sins that lead unto death? Because Paul says in Romans that they that do such things are worthy of death and because John lists the same type of sins in Revelation 21:8 whereby they that commit such sins will then be cast into the Lake of Fire, which is the Second Death).
3. Sins that do not lead unto death.
(i.e. These are sins that do not lead to spiritual death or destruction in the Lake of Fire. Such sins would include our hidden errors or secret faults as mentioned in Psalm 19:12. Such sins would include going over the speed limit a little (without thinking) and or breaking the traffic laws to rush your wife to the hospital. Such sins would be knowing that you could have done something better or good at your job but you failed to do it, etc.; In other words, they are the types of sins whereby a person falls short of the glory of God).
Anyways, with God, what you believe to be impossible is possible to do. Scripture talks about being sanctified by the Spirit and by the washing of the water of the Word. Scripture talks about us ceasing from sin. Scriptures identifies false believers as in them not ceasing from sin.
I really am struggling with the bizarre connection you make with people who say they're saved and think they can live as they please and someone who is truly saved and stumbles.
1 John 1:8 ''If we say we have no sin, we deceive ourselves, and the truth is not in us''
Hopefully my answer above will help to answer the issue if a believer stumbles on their road to overcoming sin. But nowhere does Scripture teach that a believer will forever be a slave to their sin whereby they will stumble forever.
As for 1 John 1:8: Again, the true believer is not saying they have no sin. They will admit they may at times commit sins that do not lead unto death that they may not be aware of. Some may even commit a sin that leads unto death. But they will not ignore like the Antinomian does, though. They will confess of that sin as per 1 John 1:9 says so as to be forgiven of that sinn. But the true believer will overcome sin or stop in their sinning that leads unto death, though. A believe is not slave to sin. Jesus said in John chapter 8 that he that sins is a slave to sin. He did not say this as if he was in favor with the Pharisees.
Anyways, I hope this helps.
And may God's love shine upon you today.
