"[The Kingdom of God] is like a mustard seed that a man took and planted in the garden. When it was fully grown, it became a large bush and the birds of the sky dwelt in its branches."
Consider how the Lord keeps reminding us of the resurrection that is to come, of which he has made the Lord Jesus Christ the firstfruits by raising him from the dead. Let us look at the resurrection that occurs at its appointed time. Day and night show us a resurrection; the night lies in sleep, day rises again. The day departs; night takes its place.
Let us think about the harvest; how does the sowing take place, and in what manner? The sower goes out and casts each seed onto the ground. Dry and bare, they fall into the earth and decay. Then the greatness of the Lord's providence raises them again from decay, and out of one, many are produced and yield fruit.
In this hope, then, let our hearts be bound fast to him who is faithful in his promises and just in his judgments.
-- Pope St. Clement
