Do not be mistaken: God is not contained within the church – inside its walls or any of the structures the church has put forth to try and capture God’s essence. God may be there at the church building if you carry God there with you inside yourself. Or God may be noticeably (or not so noticeably) absent. God comes and goes as God pleases, so there are many places you might find God.
Meditation helps us access and internalize the good in the universe, letting it expand within us and become a resource we carry around all the time. The way we first learn to do this internalizing of any kind of presence is through our relationships with others. The people around us when we are growing up help us form some initial internal framework of what people and reality are like. We learn others are harsh and scary or that there is great good in the world – maybe both. We then carry around these internal representations and they “help” us interpret all the other things we experience. They also help us form “rules” or “models” we unknowingly consult while interacting with the world. This all happens most of the time underneath our conscious awareness, so these internal models are having an effect all the time without us knowing it.
