Psalm 134:1

Behold, bless ye the LORD, all ye servants of the LORD, which by night stand in the house of the LORD.

Jesus speaking:

Both day and night, I call you to service. I am the High Priest of the house of your heart, your temple. And I expect you to be present with Me at all times; to be a faithful Levite, always ready to sacrifice, to stay up late, to burn the midnight oil, to wait on Me no matter how long into the night; to be a good watchman of your heart, keeping it clean and well stocked with the Word of Life. But if you aren’t being a good steward, and aren’t keeping your heart with diligence, then I might have to wake you in the night and say, “The oil is diminishing, and the Word of God in your heart is failing. Up now, run speedily, and fill thine heart with the Oil of Truth, lest your flame flicker low and go out, and you find yourself in darkness.”
