I have sometimes wondered if those occupations that some of us regard as sinful are actually sinful. Example: being one of those on cover investigators/spies. It requires lying about your identity and befriending criminals to get secret information and later betray them and get them into jail. Or what about a soldier? Or a politician in a very, VERY, corrupted country who has to make deals with corrupt people in order to get some order?
Let me be clear, I'm not saying that it is okay to compromise your faith, but we live in a corrupt world where we have to deal with corrupt people even if we don't want to, especially in some high occupations. We have to learn how to deal with them without contaminating ourselves.
But someone has to do those jobs right? To be honest, I couldn't do it, and I think there is a calling for every one of us...and just because the purpose is good at the end one should also consider the motives in our hearts.
As how I understand it, one could have the best intention in doing something, but if it's not God's will it may be a sin, a sin because we put our will before God's will and that's why we should always ask ourselves why we want to do something.
Maybe you want to be a president, but your heart is not right and you will end up being as wicked as everyone else, or maybe you want to be a soldier, which is honorable, but if you do it to escape from your life and just to have an adventure, and you don't really care what you are fighting for...I don't think that would be wise. I have seen people preaching behind a pulpit when I doubt God even called them to be pastors or leaders in a church.
I was reading a verse today that I think would apply here: To the pure, all things are pure, but to those who are corrupted and do not believe, nothing is pure. In fact, both their minds and consciences are corrupted.( Ti1:15)
If this world was led by people with pure hearts, there weren't any sinful occupations...but since that's not how it is we have to be very prayerful about what we want to do and want to be, and the reasons behind it. If you carry a pure heart, you will show purity in your job, if you carry a filthy heart, your job will be filthy.
PS.I'm not talking about occupations that are straight up sinful, like working as a drug dealer, a prostitute, a hitman,etc. I think those are OBVIOUSLY sinful, whatever the case is.
