One chooses between two basic courses for his life here on earth- the course commanded of God or "the course of this world." The Ephesians formerly followed "the course of this world". "Wherein in time past ye walked according to the course of this world , according to the prince of the power of the air, the spirit that now worketh in the children of disobedience." (Ephesians 2:2). The difference between "walking according to the course of this world" and not doing so is basically a matter of attitude. A Christian's speech, dress and activities are always tempered by a mind attuned to the will of God.
