I’m not religious but I feel something

Good. You may be in the most promising position there is — near enough to feel, free enough to be honest. Religion, at its best, is only the grammar for what you are already sensing; at its worst, it is what made you cautious of the word. Either way, the feeling did not come from religion and does not need it to survive. “The wind bloweth where it listeth” (John 3:8) — wind, not institution. It goes where it wills, and it appears to have brushed you.

Notice what the something is usually like: not a doctrine, but a nudge. An ache at certain music. An inability to be fully at home in a purely material account of things. The sense of being addressed by beauty, or by guilt, or by unexpected love. Scripture has a startling word for this: God “is not far from every one of us: for in him we live, and move, and have our being” (Acts 17:27-28) — Paul said it to pagans, in Athens, to people with no covenant and many altars. Not far. Whatever you are feeling, it is mutual, and it did not begin with you.

You do not have to become religious to follow it. Start with honesty: name the feeling to yourself in plain words, then name it to whatever is there — if you are real, meet me. That is not a creed; it is a knock. “Behold, I stand at the door, and knock” (Revelation 3:20). Doors with someone already knocking on both sides tend to open.
