What Makes Sin A Crime

In Crime and Punishment Sonya is a prostitute. But she has a Yellow Card, so technically, her profession is totally legal. The only reason that she does this, is because it is the only way that she can provide for her family. And that is the ONLY reason. She has no lust, so, even though her job is a sinful one, there is a certain of amount of purity that she still retains.
Even Raskolnikov can see this in her, he can sense it. Sonya is very shameful of her job, so she is very shy to talk to people. Rasolnikov still talks to her though. Through her, Rakolnikov, finds his purpose in life.
Just because something is a sin, does that make it a crime? That isn't always true. I mean, some can commit adultery, but that doesn't make it a crime, against the world's justice system that is. It is a crime againts God's justice system though. Man doesn't see that as a crime, but God sees that as a direct sin against Him. Man won't make you pay for that, but God will deliver His justice to you eventually. So even if you do something that isn't a crime, but if it's a sin, you will pay eventually.
Even though you may sin, and the world may not punish you for it, God eventually will. You can hide nothing from Him. Be careful with your actions, and make wise decisions in your life, what you do will eventually catch up with you, whether you like it or not.
