Habakkuk: From Protest to Praise - Trembling Yet Rejoicing

How do you deal with extreme fear?
What do you do when the fear grips you in such a way that your heart is pounding, and your legs give way?
Do you try positive thinking? Deep breathing?
Just try and push it out of your mind?
How do you exercise faith in God during the worst of times? Habakkuk says wait patiently, choose to rejoice and find your strength in the Lord.
