Several authors have done a wonderful job of defending the rationality of the Christian faith (Alvin Plantinga, N.T. Wright, Francis Schaffer, and C.S. Lewis [even though I’m not really a fan of the last] all come to mind). They have thoroughly defended the historicity of scriptural texts and the rational foundations of theistic belief in general and of Christian belief specifically. However, there is a huge difference between warranted, rational Christianity (i.e. Christian belief that is philosophically and historical defensible) and reasonable Christianity (i.e. Christianity that fits into our ‘normal’ conception of life).
I cannot count how many times someone has told me to ‘be reasonable’ about my faith. By ‘reasonable’ they meant ‘I know that you feel like God is telling you something, but you shouldn’t do it’. People told me this in college when I sold my computer to pay for a missions trip. They told me this when I changed majors, when I decided not to pursue a pastoral position, even though I had a degree in Christian Leadership. They told me this when I quit a job at Walmart to substitute teach, and when I was convinced that God was pushing me towards a 17 year old girl (I decided that I wouldn’t actually pursue a relationship until after she turned 18, but she shot me down regardless… I’ll have to write that story sometime). Each of these decisions has led me into some difficult times, but in each of them following God and allowing him to guide my life has led to significant spiritual growth and has helped me to better understand God. It is easy for us to doubt, to convince ourselves that our reasonable decisions are a better guide to life than God’s will. However, I’ve also made some reasonable decisions, even when God was telling me not to (that’s what led me to Walmart in the first place), and they have never turned out well.
While our faith is absolutely rational and defensible, it is rarely reasonable from a human perspective. If you are ever convinced that God’s will is always going to be the reasonable thing try reading Genesis, or Exodus, Ezekiel, Hoshea, personally, I think my favorite example of the unreasonableness of the Christian faith is the crucifixion. Throughout scripture God asks those who are willing to follow him to do entirely unreasonable things. To sacrifice their own happiness and well-being for his glory. To sacrifice themselves for the good of others, and to trust God in impossible situations. Remember when God told Abraham to get up and leave everything he’d ever known? No idea where he was going, or what he was going to do, just leave. Or when God commanded him to kill his only son, the son of the covenant he’d made with God? Soren Kierkegaard’s Fear and Trembling is an excellent discussion of this.
Ultimately, the greatest argument for a reasonable religion is the pursuit of comfort. The American dream tells us to pursue our own comfort, our own ends, to take care of ourselves first, and that true strength comes from taking what we want. However, scripture tells us something completely different. Scripture tells us to put God first, and then others. To pursue God’s glory rather than our comfort. To leave off our own ends and pursue the ends of the kingdom. Lastly, scripture tells us that God doesn’t value the strength to take what we want, but the weakness to put others first, even when this means allowing them to take advantage of us.
The reasonable, Americanized church often rejects these concepts. It tells us to be hard and forceful, to defend our rights rather than live up to our responsibilities. It tells us to ignore God and do the culturally acceptable thing. To focus on this world instead of the next. All to often we develop the wrong priorities and the church encourages us in this development. So, one of the most fundamentally difficult aspects of Christian living in America is to avoid the trap of easy, reasonable religion that surrounds us, and instead to pursue ‘the upward calling’ of the faith.
