John 11:9

Twelve hours in the day; an appointed season for me and all men to do the work assigned to us by God.

Walk in the day-stumbleth not; if, in its proper season, a man does that to which God calls him, he is safe, because under God's protection. The man who makes it his object to learn the will of God, and to do it, however it may affect him and his condition in this world, is like one who travels in the daytime, when he can see objects distinctly, and treat them according to their character. But a man whose great object is himself, and who seeks supremely earthly things, is like one who travels in the night, without sun, moon, or stars. He is in darkness, and liable every moment to fall and perish.
