If we were willing to make even small efforts, we would not suffer either much distress or difficulty. For if a man urges himself to make efforts, then, as he continues them, he gradually makes progress and later practices virtues with tranquillity; for God, seeing him urge himself, sends him help. So let us urge ourselves, for, although we have not reached perfection, if we make efforts, through efforts we shall receive help, and with this help shall acquire all kinds of virtues. Therefore one of the fathers said, "Give blood and receive spirit," that is, strive earnestly and you will become perfect.

(The Philokalia)
