Set your minds on things above, not earthly things.Colossians 3:2
When hearing chatter in the street, I will try to drown it all out. If I desire to be strong, I must harness what I think about.
It matters a good deal that your book-food should be strong meat. We are what we think about. Think about trivial things or weak things and somehow one loses fiber and becomes flabby in spirit. Soldiers need to be strong.
Soldiers have not time for everything. “I have no time for anything outside my profession.” a young officer said once, and in measure that is true. We can’t be entangled in the affairs of this life if we are to be real soldiers. By its affairs I mean its chatter and its ways of thinking and deciding questions, its whole aspect and trend.
