3 To you, poor little feeble man, India is far from the land of the Goths, and Spain from Persia; but to God, who holds the whole earth in the hollow of His hand, all things are near at hand. Impute not then weakness to God, from a comparison of your feebleness, but rather dwell on His power. Does then the sun, a small work of God, by one glance of his beams give warmth to the whole world; does the atmosphere, which God has made, encompass all things in the world; and is God, who is the Creator both of the sun, and of the atmosphere, far off from the world? Imagine a mixture of seeds of different plants (for as you are weak concerning the faith, the examples which I allege are weak also), and that these different seeds are contained in your single hand; is it then to you, who art a man, a difficult or an easy matter to separate what is in your hand, and to collect each seed according to its nature, and restore it to its own kind? Can you then separate the things in your hand, and cannot God separate the things contained in His hand, and restore them to their proper place? Consider what I say, whether it is not impious to deny it?
