I truly feel like the book of Psalms is my favorite. There is so much encouragement in the words. It is believed this Psalm refers to the perilous times when David fled from Saul and hid in caves (1 Samuel 22:24) David found real security not in the hidden recesses of the caves but in the shadow of God's wings (Introduction to Psalm 57, The Voice Bible, page 666)
I've never had someone try to kill me, but there have been times when I've felt like everything was against me. Someday I hope to have the same confidence David did when he wrote:
My heart is ready, O God;
my heart is ready.
And I will sing!
Yes, I will sing praise!
Wake up, my glory!
Wake up, harp and lyre;
I will stir the sleepy dawn with praise.
I will offer You my thanks, O Lord, before the nations of the world;
I will sing of Your greatness no matter where I am.
For Your amazing mercy ascends far into the heavens;
Your truth rises above the clouds,
O God, be lifted up above the heavens;
may Your glory cover the earth!
(verse 7 - 11 The Voice)
