If you have a scary dream about bugs and you can't go back to sleep, it helps to recite Psalm 23 and then repeat "The Lord is my shield" nine times- at least this was what Zeke and I came up with in the wee hours of the morning.
"I will praise the Lord, who counsels me; even at night my heart instructs me."Psalm 16:7
He is our shield most surely. We will all do well to meditate on that truth by day and by sleepless night.
