Such people, even if they were to come face to face with G-d, would find some way of rationalising it away. We are talking about people who do recognise it as a miracle. I doubt whether you would need the fingers of both hands to count them. Because it was an event where we were passive bystanders leaving G-d at the helm. And this is the connection to Rosh HaShana.
People come to shule waiting for inspiration.
They want the Rabbi to inspire them, the Chazan to uplift them, the Choir to entertain them. They compare the synagogue service to a concert or opera. They want to sit back and be inspired, entertained. Sometimes this does happen. Oy didn't he daven beautifully.
