This Psalm describes a man's intense longing for God which can only be satisfied by personal relationship with Him. Being in communion with God was David's all encompassing desire. God was the only goal!
This Psalm should cause us to pause and ask, Do I really have His presence in my daily life? Or are my days filled with secular pursuits and worldly entertainment? Is my relationship with Him confined to a certain space or time or is it a continual fellowship?
