I have need of humility
I have great knowledge in God, but I restrain myself, lest, I should perish through boasting. For now it is needful for me to be the more fearful; and not give heed to those that puff me up. For they that speak to me [in the way of commendation] scourge me. For I do indeed desire to suffer, but I know not if I be worthy to do so. For this longing, though it is not manifest to many, all the more vehemently assails me. I therefore have need of meekness, by which the prince of this world is brought to nought.
