15 Of this we have examples. Saul persecuted the members of Jesus Christ, who is now sitting in heaven; grievously did he persecute them in his frenzy, in the loss of his reason, in the transport of his madness. But He with one word, calling to him out of heaven, “Saul, Saul, why do you persecute Me?” struck down the frantic one, raised him up whole, killed the persecutor, quickened the preacher. And so again many lethargic ones are healed. For to such are they like, who are not violent against Christ, nor malicious against Christians, but who in their delay are only dull and heavy with drowsy words, are slow to open their eyes to the light, and are annoyed with those who would arouse them.
“Get away from me,” says the heavy, lethargic man, “I pray you, get away from me.” Why? “I wish to sleep.” But you will die in consequence. He through love of sleep will answer, “I wish to die.” And Love from above calls out “I do not wish it.” Often does the son exhibit this loving affection to an aged father, though he must needs die in a few days; and is now in extreme old age. If he sees that he is lethargic, and knows from the physician that he is oppressed with a lethargic complaint, who tells him “Arouse your father, do not let him sleep, if you would save his life”!
Then will the son come to the old man, and beat, and squeeze, or pinch, or prick him, or give him any uneasiness, and all through his dutiful affection to him; and will not allow him to die at once, die though he soon must from very age; and if his life is thus saved, the son rejoices that he has now to live some few days more with him who must soon depart to make way for him. With how much greater affection then ought we to be importunate with our friends, with whom we may live not a few days in this world, but in God's presence for ever! Let them then love us, and do what they hear us say, and worship Him, whom we also worship, that they may receive what we also hope for. “Let us turn to the Lord,” etc.
