The Juice of Life: God's Promises

I recently bought Francis Schaeffer's "How Should We Then Live" DVD. I must say that it has been a treat watching and hearing him explain through various epochs in history how mankind finally ended up in misery, with his pitiful attempts at finding meaning in life via humanism (notwithstanding his glorious achievements in culture), by virtue of his rejection of absolutes. Though I do not agree with Schaeffer's view of neutrality (as opposed to presuppositionalism), he does adequately describe the predicament of man when in a state of independence from God.

The following quote is something that Schaeffer would definitely agree with:

"What are you driven by? What really gets you up out of bed in the morning? When everything around you seems to fall apart and life doesn't seem to work, what anchors you? Is it things that you see (circumstances as they appear to you) or is it something that you hear (God's promise) that determines things for you? Is it something inside of you or something external to you, a word that comes from outside completely challenging your experience of things? Are you driven by power, wealth, ambition, self-esteem, the acceptance of others? Or perhaps by nobler things, like making the world a better place, loving God and your neighbor, a sense of purpose and meaning?...While affirming the importance of having clear goals and a worthy focus in life, I am urging us to put purposes in their place, as servants of promise. No longer under the law's condemnation, the justified are free now to respond to God's commands out of thanksgiving for the God whose character it displays and out of love for our neighbors. The gospel saves us, giving us reason to walk through the wilderness to the promised land, and the law guides us, giving us directions for that journey. Christians are driven by God's promises, and directed by God's purposes." (Michael Horton, The Gospel-Driven Life [Grand Rapids, MI: Baker, 2009], 133, italics original).
