A missional theology...appl ies to the whole of life of every believer. Every disciple is to be an agent of the kingdom of God, and every disciple is to carry the mission of God into every sphere of life. We are all missionaries sent into a non-Christian culture.
I believed that there was a God because I was told it by my grandmother and later by other adults. But when I found that I knew not only that there was God but that I was a child of God, when I understood that, when I comprehended that, more than that, when I internalized that, ingested that, I became courageous.
My deeply held belief is that if a god of anything like the traditional sort exists, our curiosity and intelligence is provided by such a God. We would be unappreciative of that gift if we suppressed our passion to explore the universe and ourselves.
