Yes, I beg you that I may not, when present, show courage with the confidence with which I intend to be bold against some, who consider us to be walking according to the flesh.

for the weapons of our warfare are not of the flesh, but mighty before God to the throwing down of strongholds,

throwing down imaginations and every high thing that is exalted against the knowledge of God, and bringing every thought into captivity to the obedience of Christ;
