No one is exempt from sin. Some believe that they have a license to sin once they've been saved. If you think that way, you might be lost because once you've been saved you're a new creature and will not want sin in your life. Most sin is brought about by the lust of the flesh. It's not a sin to have nice things or things that you want but if God said not to have it, it's a sin to have them because you disobeyed Gods Word. The devil watches and knows what your tempted with and will use those to pull you away from God. Once you take action on covetousness then you've made a choice therefore conceiving sin. Being by yourself means you have no accountability and you're likely to stumble more often. Being idle too long will cause one to fall into sin. Surrounding yourself with other Christians will keep you from sinning than being left alone. Anything that you've got to hide in secret is wrong. So if you can't tell anyone else about it or do it in secret, then you need to ask God if it's of Him. What good is sin and how does it benefit us? If one brings sin into their life it WILL affect everyone around them. Sin will ALWAYS bring forth death, always have, always will.
