Book Excerpt: The Audacity of Hope

......Almost by definition, faith and reason operate in different domains and involve different paths to discerning truth.

The story of Abraham and Isaac offers a simple but powerful example. According to the Bible, Abraham is ordered by God to offer up his "only son, Isaac, whom you love," as a burnt offering. Without argument, Abraham takes Isaac to the mountaintop, binds him to an altar, and raises his knife, prepared to act as God has commanded. Of course, we know the happy ending—God sends down an angel to intercede at the very last minute. Abraham has passed God's test of devotion. He becomes a model of fidelity to God, and his great faith is rewarded through future generations. And yet it is fair to say that if any of us saw a 21st century Abraham raising the knife on the roof of his apartment building, we would call the police; we would wrestle him down; even if we saw him lower the knife at the last minute, we would expect the Department of Children and Family Services to take Isaac away and charge Abraham with child abuse. We would do so because God doesn't reveal Himself or His angels to all of us in a single moment. We do not hear what Abraham hears, do not see what Abraham sees, true as those experiences may be. So the best we can do is act in accordance with those things that are possible for all of us to know, understanding that a part of what we know to be true—as individuals or communities of faith—will be true for us alone.

This is not to say that I'm unanchored in my faith. There are some things that I'm absolutely sure about—the Golden Rule, the need to battle cruelty in all its forms, the value of love and charity, humility and grace.
