The lion has roared, who will not fear? the Lord GOD has spoken, who can but prophesy?
Read Chapter 3
Augustine of Hippo
AD 430
“Lord, you have been our refuge.” Therefore we have recourse to you. Our healing shall be from you, for our evil is from ourselves. Because we have abandoned you, you have abandoned us to ourselves. May we therefore be found in you, for in ourselves we had been lost. “Lord, you have been our refuge.” Why, my brethren, should we doubt that the Lord will make us gentle if we submit ourselves to be tamed by him? You have tamed the lion, which you did not create. Will your Creator be unable to tame you? What is the source of your power to tame such savage beasts? Are you their equal in bodily strength? By what power then have you been able to tame such huge beasts? The socalled beasts of burden are wild by nature, for if untamed they could not be endured. But because you are not accustomed to see them except when handled by men and under the curb and control of men, you might think that they were born tame. At any rate, consider the savage beasts. The lion roars; who does not fear? And yet...
In other words, he is saying, if by the roaring of the lion, the strongest of wild animals, a person would not be so unfeeling and insolent as not to feel the impact of terror, how could it be that when God speaks in His great might and bids them proclaim what they have been told, they would not be in fear of the bidder?
