Scripture:
[3] But you, Lord, are a shield around me, my glory, the One who lifts my head high.
[4] I call out to the Lord, and he answers me from his holy mountain.
[5] I lie down and sleep; I wake again, because the Lord sustains me.
[6] I will not fear though tens of thousands assail me on every side.

Observation:
As David wrote this, he was running from his own son who conspired against him with armies.  He had plenty of reason to despair and be afraid but what does he do?  He gives glory to God as his protector.  He calls out expectantly.  He gives glory to God for his sleep, for his sustenance, and for his waking breath.

Application:
We may not be running from armies of thousands chasing us, but it may seem like that sometimes.  Like everywhere we turn someone or something is against us, trying to steal our happiness – troubles with our job, troubles in our families, seeing loved ones in pain, or whatever the case may be.  But our joy comes from the Lord at all times.  Let us turn to Him, knowing that even in the midst of our troubles He can give us peace that allows us to sleep at night, and the strength to get up in the morning to face the world.

Prayer:
Lord help me turn to You in times of trouble and pain.  I know You are my strength and my source of joy.  Help me Father to sleep well tonight knowing that you are my strength.  Amen
