I feel like this passage is especially valuable in a period most college ministers see as pretty vital to the success of their school year:

Unless the Lord builds the house,
    those who build it labor in vain.
Unless the Lord watches over the city,
    the watchman stays awake in vain.
It is in vain that you rise up early
    and go late to rest,
eating the bread of anxious toil;
    for he gives to his beloved sleep. (Psalm 127:1-2)

It’s not that you don’t need to work hard right now – you do. It’s just that you need to be able to lay your head on your pillow at night with the understanding that God’s got this covered as He sees fit.
