An old man used to say, “We do not advance because we do not know our capacity, and we have not sufficient patience in the work which we begin, and we wish to possess spiritual excellences without working for them, and we go from place to place, and expect to find some spot where Satan is not, and when we see the temptation of Satan in that place to which we have been called, he who knows what the war is will remain in God. For the kingdom of heaven is within you.
