Mr. Wright detects an evolution toward an image of God as a more beneficient and universal deity, one whose moral compass favors compassion for humans of whatever race or tribe, one who is now firmly in the antigenocide camp. Mr. Wright’s focus is not on whether God exists, but he does suggest that changing perceptions of God reflect a moral direction to history  and that this in turn perhaps reflects some kind of spiritual force.

“To the extent that ‘god’ grows, that is evidence  maybe not massive evidence, but some evidence  of higher purpose,” Mr. Wright says.

Another best-seller this year, Karen Armstrong’s “The Case for God,” likewise doesn’t posit a Grandpa-in-the-Sky; rather, she sees God in terms of an ineffable presence that can be neither proven nor disproven in any rational sense. To Ms. Armstrong, faith belongs to the realm of life’s mysteries, beyond the world of reason, and people on both sides of the “God gap” make the mistake of interpreting religious traditions too literally.

“Over the centuries people in all cultures discovered that by pushing their reasoning powers to the limit, stretching language to the end of its tether, and living as selflessly and compassionately as possible, they experienced a transcendence that enabled them to affirm their suffering with serenity and courage,” Ms. Armstrong writes. Her book suggests that religion is not meant to regrow lost limbs, but that it may help some amputees come to terms with their losses.

Whatever one’s take on God, there’s no doubt that religion remains one of the most powerful forces in the world. Today, millions of people will be giving thanks to Him  or Her or It.

Another new book, “The Faith Instinct,” by my Times colleague Nicholas Wade, suggests a reason for the durability of faith: humans may be programmed for religious belief, because faith conferred evolutionary advantages in primitive times. That doesn’t go to the question of whether God exists, but it suggests that religion in some form may be with us for eons to come.

I’m hoping that the latest crop of books marks an armistice in the religious wars, a move away from both religious intolerance and irreligious intolerance. That would be a sign that perhaps we, along with God, are evolving toward a higher moral order.
