Watch this before reading further:
In referencing this song, I recognize that there is a distinction to be made between the romantic nature of this song and the spiritual nature of what follows. Both songs in the mash-up are romantic in nature, but the joy and happiness that is expressed in the songs is unique because it is joy and happiness that is present in spite of the nasty and depressing circumstances that are surrounding the individual singing. I am convinced that as a Christian, the joy and happiness that I experience as a result of my relationship with God through Christ is exactly like this. Yes, there are difficulties and hard times in life, but I can take joy and experience happiness in spite of those things. But as this very old prayer expresses very eloquently, that joy and happiness can only truly come from the God of the Bible:
O LORD, Help me never to expect any happiness from the world, but only in thee. Let me not think that I shall be more happy by living to myself, for I can only be happy if employed for thee, and if I desire to live in this world only to do and suffer what thou dost allot me. Teach me that if I do not live a life that satisfies thee, I shall not live a life that will satisfy myself. Help me to desire the spirit and temper of angels who willingly come down to this lower world to perform thy will, though their desires are heavenly, and not set in the least upon earthly things; then I shall be of that temper I ought to have. Help me not to think of living to thee in my own strength, but always to look to and rely on thee for assistance. Teach me that there is no greater truth than this, that I can do nothing of myself. Lord, this is the life that no unconverted man can live, yet it is an end that every godly soul presses after. Let it be then my concern to devote myself and all to thee. Make me more fruitful and more spiritual, for barrenness is my daily affliction and load. How precious is time, and how painful to see it fly with little done to good purpose! I need thy help: O may my soul sensibly depend upon thee for all sanctification, and every accomplishment of thy purposes for me, for the world, and for thy kingdom.
