I can state that one can't prove the existence of God simply because "miracles" happen.
One can believe that God makes miracles to happen, and have faith as a corollary.
An interesting theological concept I have been entertaining recently is that God is Pure Being, not the noun form (we see objects), but the verb form, as in fully being or “beingness.” We do, and do, and do. From this cognitive frame (God as Beingness), it is not God’s action that makes a miracle, but our action of CHANNELING Ultimate Being (Beingness). Interesting that the source of our own action is our own being. All action is made possible by our physical existence, our incarnation. To the extent that our actions flow mindfully from our being we achieve more coherence, harmony, sense of meaningfulness. Same as Christ’s advice to give with a glad heart (the “heart” being our beingness that is not defined by any one, relative, thing, but instead is a kind of ineffable wholeness from which all our particular actions and characteristics emerge, arise out of, become manifest.).
My thanks to Will’s “wimpy” religious orientation. In my preceding reply (to him) on this thread, I spontaneously blurted out the phrase “orientations of being.” This, as a possible substitute for the concept of “belief.” While physical existence kind of forces, traps, or “throws” (an Existential philosophy term) us to act, often brashly or too quick to be mindful, aware, there might be a being-rich action that might be more like an orientation or “lean,” than a more-or-less irreversible action. Would a mere orientation be considered “wimpy” to an action and answer oriented personality? Probably. But to me it allows room to breathe. And breathing is a concept and experience behind the word “spirit.” Breath interconnects , overlaps. Spooky action at a distance. The stuff of miracles.
