Many in the modern Church in the west find it hard to accept many doctrines in the Bible in the Bible what it says. They love to qualify, read into it, or to bend it. This itself a vile, evil despicable sin, worthy all of condemnation, and yes, public condemnation. It is like dirt in one's mouth, worthy only of being spat out of one's mouth.
Why is it that so many in the modern western Church find it hard o accept so many doctrines, such that they border of becoming the "unstable and ignorant people" who twist the Scriptures to their own destruction 2 Peter 3:16 describe? Why? Because of their sin which is still in them and not mortified.
You may say "we are all sinners". Well, that was the case before you were saved, and indeed the only thing you could do if you were not saved (Romans 6:20; John 8:34). But now you are no longer a sinner, if you are true Christian: Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new (2 Corinthians 5:17).
You not only have no excuse to simply say you are a sinner and cannot help it but sin. You now as a slave of Christ must submit to Christ fully (Romans 6:6,18; 1 Corinthians 7:22). Submission to Christ is unqualified, fully and absolute submission.
You either fully, absolutely submit to Christ, or you don't. There is absolutely no in between.
There is no such thing as a "small" sin or "a bit" of disobedience or unsubmission. All sins, including the failure to submit to Christ fully, even to the slightest, are vile despicable sins, worthy of Hell-fire and hatred from God. That includes the sins of the true follower of Christ.
