My Heart Shall Not Fear

Psalm 27:1-3

1  The LORD is my light and my salvation; whom shall I fear? the LORD is the strength of my life; of whom shall I be afraid? 
2  When the wicked, even mine enemies and my foes, came upon me to eat up my flesh, they stumbled and fell. 
3  Though an host should encamp against me, my heart shall not fear: though war should rise against me, in this will I be confident.
