This song reveals the unconscious and conscious passion and need of every believer and unbeliever- which is to know God and we can never finish our quest of knowing God in a life time because He contains alot of which we entirely depend on for our all round growth and fulfillment of purpose in life. Remember God said his people are perishing for lack of knowledge. This is because they don't know him. So therefore this songs has it's purpose to direct our focus on the solution of knowing God.
