Hope in God is more important than life itself

Psalm 39:4, 6-7

Lord, make me to know mine end, and the measure of my days, what it is: that I may know how frail I am. Surely every man walketh in a vain shew: surely they are disquieted in vain: he heapeth up riches, and knoweth not who shall gather them. And now, Lord, what wait I for? my hope is in thee.
