This is not new. The Age of Enlightenment showed us that an unknowable God is questioned, and that science and man can become the new religion.
Faith is a gift that many do not have.
I, myself, find myself always questioning, but always hoping that there is a God who loves us and surrounds us.
Then, out of nowhere at the least discernible moments, I sense His presence and faith comes rushing in like air crashing into itself after lighting breaks it apart and the clap of thunder signifies not only the existence of air but its awesome effects.
