Paul, in writing to the Philippians, had this to say to them:
Philippians 4:8 Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things. 9 Whatever you have learned or received or heard from me, or seen in me—put it into practice. And the God of peace will be with you.
I like reading a number of books by one author, then moving on to another author and reading a number of that person's books, and so on.
One time I was reading some books written by Tami Hoag. After having finished my third one, I realized I was feeling rather "dragged down" and pessimistic, not my usual optimistic happy self. It wasn't until I started the fourth book that it occurred to me what was happening.
All these books had a kind of sameness to them... they were all rather seedy, depicted coarse and vulgar characters, and kind of wallowed in poverty, ugliness, crime and unpleasantness.
I then wondered what on earth I was doing reading this kind of stuff if it was dragging me down. I didn't bother to finish the 4th book and I have not read any more of them since.
I think the apostle Paul was on to something with his words to the Philippians. We know the saying "you are what you eat" but I think the same can be said to some extent about what else you put in your body, or in this case, into your mind.
If you spend a lot of time immersing yourself in stuff that a wee voice from your conscience starts niggling you over, questioning if this is really wholesome and constructive and healthy for you, then you are probably putting yourself at risk of dragging yourself down.
Changing your diet of books, magazines, movies, computer games, whatever, to something more "pure" (noble, lovely, admirable, excellent, praiseworthy, etc) - or just right off whatever subject that affects you unduly - can help swing you into a better state of mind with less direct temptation to sin.
We are actually called by God to pursue righteousness, not to stay stuck in those things that tempt us away from Him.
2 Timothy 2:22 Flee the evil desires of youth, and pursue righteousness, faith, love and peace, along with those who call on the Lord out of a pure heart.
That's really hard, I know, but it is what is asked of us regardless.
So, back to your original question, AM, and maybe your answer is already there if you listen to your conscience and especially if you read more of Paul's letters to the early churches where he gives lots of divinely inspired advice on how a follower of Christ is to conduct himself. If the answer is that these things do not cause you to sin, then they might well be safe for you. But keep asking yourself... do they lead you towards righteousness, faith, love and peace? That will be the real test of your answer. I do not know your answer for you, but I suspect you will discover it yourself if you are prepared to listen to that little voice inside you.
I hope this response is of some help to you.
