Paul is standing in Athens surrounded by altars to gods nobody has met. He is not mocking the city. He is telling its people that the searching itself was arranged.
Luke says Paul was troubled by how full of idols the city was. He argued in the synagogue and in the marketplace every day, and eventually the philosophers brought him to the Areopagus to explain himself. He began with an altar he had passed, one set up to a god the Athenians admitted they did not know. He did not tear it down. He started there.
God intended that they would seek Him. The reaching was not an accident of human restlessness. It was designed into the situation.
Then the phrase that carries the verse. Though He is not far from each one of us. Not far from the crowd in general. From each one, which in Athens included people who had the theology entirely wrong and were building monuments to their own uncertainty.
Think of the search bar at one in the morning. You type a question you would not ask out loud. Then a video, then another, then a comment thread full of people just as unsure as you are. You close the laptop no closer than when you started, and a little embarrassed that you looked.
Perhaps reach out for Him and find Him. The word translated reach out is what you do in the dark, hands out, feeling for a wall.
If that is what your faith looks like right now, groping rather than seeing, the verse does not treat it as a failure. It treats it as the expected posture and then says the distance is short.
The speech ended with mixed results. Some sneered, some wanted to hear more later, and a few believed. Paul did not treat any of them as beyond reach.
Reach anyway. Tonight, instead of the search bar, say the question to God directly, in the words you would have typed. Then read one of the Gospels for ten minutes and see who you find there.
