The Human condition is such that we may find ourselves in the valley of desiring something more, its in those valleys we must remember He can and most assuredly will satisfy our thirst.
For he satisfieth the longing soul, and filleth the hungry soul with goodness. Therefore he brought down their heart with labour; they fell down, and there was none to help. Then they cried unto the Lord in their trouble, and he saved them out of their distresses.
