I am describing my own religious life from the time I went to Harvard until my late 40s. At that point, my wife, prompted by the birth of our first child, had found a religious tradition in which she was comfortable, Quakerism, and had been attending Quaker meetings for several years. I began keeping her company and started reading on religion. I still describe myself as an agnostic, but my unbelief is getting shaky.
Taking religion seriously means work. If you’re waiting for a road-to-Damascus experience, you’re kidding yourself. Getting inside the wisdom of the great religions doesn’t happen by sitting on beaches, watching sunsets and waiting for enlightenment. It can easily require as much intellectual effort as a law degree.
Even dabbling at the edges has demonstrated to me the depths of Judaism, Buddhism and Taoism. I assume that I would find similar depths in Islam and Hinduism as well. I certainly have developed a far greater appreciation for Christianity, the tradition with which I’m most familiar. The Sunday school stories I learned as a child bear no resemblance to Christianity taken seriously. You’ve got to grapple with the real thing.
Start by jarring yourself out of unreflective atheism or agnosticism. A good way to do that is to read about contemporary cosmology. The universe isn’t only stranger than we knew; it is stranger and vastly more unlikely than we could have imagined, and we aren’t even close to discovering its last mysteries. That reading won’t lead you to religion, but it may stop you from being unreflective.
