“How Should We Then Live?’ asks the provoking title of Francis Schaeffer’s documentary which bears the sub-title ‘The Rise and Fall of Western Thought and Culture.’ The documentary is an expression of Schaeffer’s defense of Presuppositional Apologetics—the view that Christian faith is the only basis for rational thought. Remove that basis and rational thought decays. It’s a bold presupposition, isn’t it?
We all make sense of our experiences from presuppositions we hold. That is why two observers seeing the same thing can come away with two very different impressions. These suppositions, inferences, even hunches create the worldviews through which we make sense of everything we observe. Christian faith, explains Presuppositional Apologetics, presupposes the universe, the Bible, and Jesus, the Son of God are divine revelations without which every other worldview is lacking essential information for rational human life. There are no neutral assumptions from which reason can arise. Only the assumptions that arise from God’s revelation provide us with full rational thought that leads to full flourishing life.
As the psalmist brings us to his concluding stanza of Psalm 119, he summarizes Scripture’s teaching on the personal nature of God. He connects his experience of God with the rational basis of human thought: the Scriptural revelation that God alone is worthy of worship, that God’s precepts alone are faithful guideposts for life, and that God has created one salvation, the ultimate solution to every human problem.
“May my cry come before you, O LORD; give me understanding according to your word. / May my supplication come before you; deliver me according to your promise. / May my lips overflow with praise, for you teach me your decrees. / May my tongue sing of your word, for all your commands are righteous. / May your hand be ready to help me, for I have chosen your precepts. / I long for your salvation, O LORD, and your law is my delight. / Let me live that I may praise you, and may your laws sustain me. / I have strayed like a lost sheep. Seek your servant, for I have not forgotten your commands” (Psalm 19:169-176).
“Give me understanding according to your word,” pleads the psalmist. He is convinced that the wealth of wisdom (rational thought and the behaviours that arise from it) for the present, and hope for the future come from God. As modern thinkers, we may be tempted to think social consensus or political charters make Scriptural revelation obsolete. But can charters of rights and freedoms really trump the noble virtue God’s character and principles express? What about when society or nature and their current cohort of ‘freedoms’ and restrictions fail us?
The psalmist’s hope is in the Lord. “May your hand be ready to help me,” he prays, and “I long for your salvation…” So the psalmist guides us to look to the Hope of the Nations, the Lord’s salvation—Jesus—who alone offers a rational basis for believing that there is hope for us.
How ought we live each day in order to reflect the rational foundation of our faith? By coming to the Shepherd of our souls admitting we are “strayed…lost sheep” and “servant(s)”, and asking for His help to live lives of integrity, lives aligned with the truth of His revealed will. That is the message the psalmist has painstakingly taken 176 verses in twenty-two stanzas to communicate. Without God we are nothing. With His salvation we become everything He imagined. That’s more than epic. That’s rational.
