Just a thought: It is important for Christians to focus on holy things, and not allow ourselves to be more influenced by the world than by God’s Word.
One obvious way to stay focused on God is to study our Bibles. Other ways to keep our thoughts pure and to continue being transformed and renewed as we’re instructed to be in Romans 12:2, are to read books and articles by sound, faithful members of the body of Christ, and to listen to (and sing along with) spiritually uplifting songs.
What you put in is what you will think about. What you think about, is what will come out.
