Well, the sins in fact can be. A mindset like “ah, I know the system, I can presume on so much mercy that the Lord will never care where I progress or do anything to further my progress” — misses the point.
Yes in fact the Lord will forgive even that you stole the bike. But the bible’s answer is “stop stealing, and instead work with your hands so that you may have something to share with those in need.” The gesture of the bishop towards the thief in “Les Miserables” is an example of kick starting that.
