Psalm 3

LORD, how many are my foes! How many rise up against me! Many are saying of me, “God will not deliver him.”
But you, LORD, are a shield around me, my glory, the One who lifts my head high. I call out to the LORD, and he answers me from his holy mountain. I lie down and sleep; I wake again, because the LORD sustains me. I will not fear though tens of thousands assail me on every side.
Arise, LORD! Deliver me, my God! Strike all my enemies on the jaw; break the teeth of the wicked. From the LORD comes deliverance. May your blessing be on your people.
Psalm 3

I love how David describes God.

But you, LORD, are a shield around me

A shield doesn't just protect a warrior, it defines him.

In the middle of a battle, everyone is wearing similar armor; they look the same...so how would someone know if their friend was approaching them or an enemy? By their shield. The shield bears the warrior's family crest it protects them against attackers, but it also protects a warrior from his own friends.

When people look at us, they should see faithful bearers of God's mark. That's people identify us.

I wake again, because the LORD sustains me.

How often do you wake up and praise God because he gave you another day to live, another day to bear his crest? Life is a beautiful gift. Don't live fearful of the day your life ends, but don't forget to praise God for the life he's given you. 

my God is my rock, in whom I take refuge, my shield and the horn of my salvation. He is my stronghold, my refuge and my savior— from violent people you save me.
2 Samuel 22:2
