I know you were talking to
@Ferris Bueller there...but I kind of think that you think that you are talking to both of us, so I will respond.
I have indeed, also, been on both sides of this argument.
And, when I was on your side of it, there were sins that I felt free to commit and didn't feel a qualm of conscience about committing them. I would just confess them every time and think that that covered it.
Then I spent some time in prayer to the Lord and asked Him to show me something in the Bible that would help me to stop those sins. And He led me to Ezekiel 33:11-20. In fact, it came up the next day in my systematic reading of the Old Testament.
It showed me that sin is more serious than I had previously thought. And it woke me up.
So, when I preach the passage in question, people will respond by saying, "That is in the Old Testament and it is not valid today".
Nevertheless, the Holy Ghost spoke to me through that passage and gave me truth...truth that has set me free.
Fact is, 2 Timothy 3:16 is talking about the Old Testament...and so is 2 Peter 1:3-4.
All scripture (in the Old and New Testaments) is given by inspiration of God and is profitable for doctrine, for reproof, for correction, and for instruction in righteousness...it contains promises that will help us to be partakers of the divine nature.
That is the bottom line.
So, perhaps you ought to take a second look at the passage in question (Ezekiel 33:11-20) and ask the Lord if maybe it is the truth that will set you free...
Because I am almost certain that because you carry the doctrine that you carry, you are very much like I used to be...making excuses for a sinful lifestyle and committing sins that you think you are getting away with.
Chances are the Lord is not chastening you for these sins...because you may very well be illegitimate and not a true son...so you are going along thinking that you are somehow holy because of the lack of chastening when it may simply be true that you are not a subject of His chastening because you are not His...
At least, that is one of the ways that a man might see it who is looking at it from the outside.
You may in fact be very much a child of God...and perhaps He chastens you severely over the sins that you commit on a regular basis....because I believe that at one point you testified that you do commit sins on a regular basis.
Does He chasten you over them?
If He doesn't, then the Bible teaches us that you are illegitimate and not a true son (Hebrews 12:5-11).
Better get your heart right if that is the case.
