When we are most centered, grounded, connected, we feel in touch with a power beyond ourselves. Let's approach it differently and, for me, more centrally, because we can start with a fact. Jesus was a great historical figure, a teacher and leader who epitomized a way of life for which the central characteristic is unconditional love. Jesus stood firmly in the Jewish tradition, as did his immediate followers, and so he emphasized that heritage and used its scriptures, which he modified and refined to replace law with love. The kingdom of God is within.
Love is universally applicable.
Love is healing. Grace is to be found in every facet of life. When I am most in touch with myself, I am closest to God. This is not to say that God is all and in all. I suspect that he meant it the other way around, but he does leave himself open to my question.
