David knew God was always by his side. In Psalm 16:8 David says, I have set the Lord always before me. Because he is at my right hand, I will not be shaken. The world could be coming down around him with David standing alone, but he always walked as though God were standing right beside him through it all. Let us all live our lives knowing we are not alone. God loves us and never leaves us whether we choose to realize it or not.
