One of the greatest dangers to Christians in modern America is worldliness. And yet, in this day and age, if a sincere pastor declares that God requires His people to live holy and separated lives, his words are often dismissed as legalistic, or worse, as an attack on the grace of God. But the Word of God tells us that if we are a friend of the world, we make ourselves enemies of God. The biblical call to holiness must not be dismissed, but properly understood and then lived out.
