We need holy places to help cultivate our sense of the sacred. By spending time in places connected with sacred history or set aside for worship we develop a capacity to see the glory of God in every bush. This is holy ground. But the deeper truth is that every step we take is on holy ground. It's all holy. There are no non-sacred places, only sacred places and desecrated places. But it’s specific “holy places” that lead the way to seeing all places as holy. It's the practices of prayer, pilgrimage, and contemplation that help alert us to the fact that we live our lives on holy ground.
