(Proverbs 12:6 KJV) The words of the wicked are to lie in wait for blood: but the mouth of the upright shall deliver them.
How many “words” (1697) of the “wicked” (7563) are lurking in your home? By that I mean how many books, videos, albums or games are in your house just waiting for an unsuspecting mind to open itself? As a mature adult I don’t worry about the books on my shelf. There are works of literature that I have read to be informed. That is part of being wise, knowing what the other side thinks. But there is a caution I would suggest.
Do you have any children around that are susceptible to nonsense? I have read the Koran. I have read Atlas Shrugged. I have read a lot of science fiction. If I had young children they would be among the titles I would not have in my house. Be wise.
One reason Christians understand the world better is because we are totally surrounded by the thinking of the other side. The pagan God haters control just about every source of information we have. If we are on track we spend time each day in the word so we have a solid foundation to resist and interpret their nonsense but it does not happen automatically.
So? Be alert when you pick up a book on history or a source of news. Be like the home owner wondering what color paint to buy. He takes a sample of what he is trying to work with and uses it as the basis of his decision. The word is your color sample.
