Psalms 73:26-27

My flesh and my heart may fail, but God is the rock and strength of my heart and my portion forever.  For behold, those who are far from You will perish; You have destroyed all those who are unfaithful and have abandoned You.  

God is our strength when we feel weak and our direction when we are lost.  We know this because we remember our lives before salvation and what it felt like not knowing God.  That feeling of separation and lack of guidance is why people perish without God.  Praise and thanksgiving to our father in heaven for His love and salvation.
