'Affairs of This Life' in the Bible

Know ye not, that we shall pass judgment upon angels? How much more, concerning affairs of this life?

Why, then, if you have cases relating to the affairs of this life, do you set to try them men who carry no weight with the Church? To your shame I ask it.

No soldier on service entangleth himself in the affairs of this life; that he may please him who enrolled him as a soldier.
