Lactantius

“ God made the world on account of man. He who does not see this, does not differ much from a beast. Who but man looks up to the heaven? who views with admiration the sun, who the stars, who all the works of God? Who inhabits the earth? ”

“ The world was made by God, that men might be born; again, men are born, that they may acknowledge God as a Father, in whom is wisdom; they acknowledge Him, that they may worship Him, in whom is justice; they worship Him, that they may receive the reward of immortality; they receive immortality, that they may serve God for ever. ”

“ Therefore God is to be worshipped, that by means of religion, which is also justice, man may receive from God immortality, nor is there any other reward of a pious mind; and if this is invisible, it cannot be presented by the invisible God with any reward but that which is invisible. ”
