If you think about it, religion is just what the human soul acts like when God is around. And just like gravity is everywhere, people can’t really escape from religion. Of course, people react differently according to how they act to whatever situation…but they still react.
Thing is, people’s reaction to God can only go down three different religious ways: head, heart or will. It’s like the basis of every religion and people wind up dabbling in any of these, or a mixing of them.
That’s just religion but then we get to the source of religion. You either have religion that comes from God or religion that comes from people. So God’s religion would be religion that he tells you about, and takes in all three spheres, or it would be religion he doesn’t tell you about—and people make up—and dabbles in all three spheres.
