“Surrender your heart to God, turn to him in prayer, and give up your sins— even those you do in secret. Then you won’t be ashamed; you will be confident and fearless. Your troubles will go away like water beneath a bridge, and your darkest night will be brighter than noon. You will rest safe and secure, filled with hope and emptied of worry.” 

Job 11:13-18

So stay alert. You have no idea when he might arrive.
