It's fashionable among some sinful Christians to proclaim with grand humility, what great sinners they still are.
The flip side of such profoundly stated unworthiness, that is more bold than humble, is: They also claim they now really really 'hate' it while sinning, than enjoying it as before. What? Their salvation only takes all the fun out of sinning, but not the sinning?
The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.
As one of their own so zealously puts it:
"We all —except you, apparently— admit to our own sinful horror, and shrink from it in pain and sorrow,"
Aside from all the shrinking, it speaks of how they hate what they are doing so much, that they are absolutely horrified by it.
First off, in the Bible, loving righteousness and hating iniquity, is by doing righteousness and not doing iniquity.
Thou hast loved righteousness, and hated iniquity; therefore God, even thy God, hath anointed thee with the oil of gladness above thy fellows.
In any case, let's look at what the Bible says about the sinner while sinning:
Choosing rather to suffer affliction with the people of God, than to enjoy the pleasures of sin for a season;
Traitors, heady, highminded, lovers of pleasures more than lovers of God;
For we ourselves also were sometimes foolish, disobedient, deceived, serving divers lusts and pleasures, living in malice and envy, hateful, and hating one another.
So, who are we to believe? The sinful person saying they really hate their sinning, or God declaring they actually enjoy it?
Nowhere does God in the Bible ever speak of anyone hates it while sinning against Him. David certainly hated the condemnation of God for sinning, but no one doubts he enjoyed it with Bathsheba, In fact, he enjoyed it so much, that he had her husband killed, so that he could keep on enjoying it.
