2 Corinthians 10:1-5

Now I, Paul, myself, appeal to you by the meekness and gentleness of Christ — I who am humble among you in person but bold toward you when absent. I beg you that when I am present I will not need to be bold with the confidence by which I plan to challenge certain people who think we are living according to the flesh. For although we live in the flesh, we do not wage war according to the flesh, since the weapons of our warfare are not of the flesh, but are powerful through God for the demolition of strongholds. We demolish arguments and every proud thing that is raised up against the knowledge of God, and we take every thought captive to obey Christ.
