And the divine apostle furnishes the rule for the Gnostic in these words, writing as follows: "For I have learned, in whatsoever state I am, to be content. I know both how to be abased, and I know how to abound. Everywhere and in all things I am instructed both to be full and to be hungry, both to abound and to lack. I can do all things through Him who strengtheneth me."
Suffering poverty is often thought to be a tribulation, but abundance also may be an occasion for tribulation. The wise person restrains himself from being enervated by abundance.
"Not that I speak in respect of want." I said, saith he, "now at length," and I rebuked you, not seeking mine own, nor censuring you on this account, as if I were in want: for I sought it not on this account. Whence is this, O Paul, that thou makest no vain boasting? To the Corinthians he saith, "For we write none other things unto you, than what ye read or even acknowledge." And in this case he would not have spoken to them so as to be convicted, he would not, had he been making boasts, have spoken thus. He was speaking to those who knew the facts, with whom detection would have been a greater disgrace. "For I have learnt," saith he, "in whatsoever state I am, therein to be content." Wherefore, this is an object of discipline, and exercise, and care, for it is not easy of attainment, but very difficult, and a new thing.
All sorts of people indeed can suffer poverty, but to “know how to suffer poverty” is a mark of greatness. Likewise, who is there who may not abound? But to “know how to abound” belongs to none but those who are not corrupted by abundance.
