How do we know when we are on sacred ground? Being sensitive to the touch if the holy or sacred in our lives takes practice. It is not something we can just expect to happen to us. We need to develop being attuned to the sacred by intentionally going out and expecting to find it.
When you go to the store do you listen or observe others? Or when you are walking are you listening to pick up all the sounds or sights around you? Or when you are talking with someone else are you looking for what might have been truly important in sharing with one another?
See the holy is all around us. Developing the sensitivity to know we have had an encounter with the sacred in our day is our own intentional sensitivity to what is going on around us. It takes practice or exercise. Try to start today. It will deepen your walk with God and all of creation.
