2 Corinthians 10:1-3

I, Paul, myself entreat you, by the meekness and gentleness of Christ—I who am humble when face to face with you, but bold toward you when I am away!— I beg of you that when I am present I may not have to show boldness with such confidence as I count on showing against some who suspect us of walking according to the flesh. For though we walk in the flesh, we are not waging war according to the flesh.
