I did kind of start off that way by saying this “the Bible says many things that can be taken many ways, that is why Jesus established a Church not a Bible” and then he came back with John 14:13-14. The thing is he seems open to maybe believing in God but he just needs some evidence. He seems to need to see that everything in the Bible is literally accurate to order to believe. I blame that on the misrepresenting of Christianity from our Protestant friends.
Warning: This reply is long and somewhat dense.
Evidence? Of what, God’s existence? The very essence of that question misses the point. Tell him God, though he is a subject, isn’t a particular. Rather he is, as the great 20th century Lutheran theologian Paul Tillich mentioned several times, “the ground of being” or “being-in-itself”. The question shouldn’t be “does God exist?” but rather “is God existence?”. Or, to ask it another way, “is existence God?” God is simply a name we give to that pure act of being-in-itself. It carries no baggage. It simply
is.
Now, is that entity the Christian God? That is a different matter. If God is the ground of being, for sake of being eternally “first” and necessary, then everything that we know to exist as a particular (this hydrogen atom, that quark) exists as an effect of the cause who is God. Or, to say it another way, exists be-cause of God. The act of bringing a particular into existence,
ex nihilo, requires either an omnipotent act of randomness or an omnipotent act of the will. Because existence is constant (I would not cease to exist on account of existing, but rather on account of ceasing to participate in existence), we can safely discard the prior. God is, in this sense, an uncreated and omnipotent subject who/which can “will” particulars into being.
Because we can only speak in human terms, and we cannot exhaust the “personality” of God without trying to anthropomorphize her/him/it, I must speak in a balanced apophatic and cataphatic way. God is both creative (by virtue of being a creator) but only because I can say he is unchanging (by virtue of being-in-itself). What kind of human person is creative, but unchanging? None! Only God. Already, we can see how logic is developing into theo-logic. It makes no sense in terms of particulars, but it somehow isn’t illogical, because you watched how we logically got there. We could also say God is Truth: statements about things or ideas are true because they are real. God is reality-in-itself, which renders him Truth-in-itself, and reality is a creative expression of that truth. At the same time, God is unknowable in essence, because she is uncreated and not a particular for sake of being-in-itself. That is to say, we cannot fit her in any
single category because we only know of particulars. We can talk
about him, but we talk
of him, so to speak.
Insofar as existential experience is concerned (the experience of being conscience, as a single person), we can speak of existence as the basis of life. Participation, in a very specific way, in the being-ness of God elicits life. We are alive in a very specific way, beyond the experience of animals, and certainly beyond the abiotic “life” of inanimate objects (which have none). But even further than that, God could be considered life-in-itself, as it is the super-universal subject of being-in-itself. That is to say God is, theoretically, so infinitely far above our experience that she transcends experience itself as a particular. He is the transcendent life-in-itself, while being the immanent source of it. God is life, soul, pneuma, etc. The Greeks knew this several thousand years ago. They were no dummies.
But what is so interesting about Christianity? The one thing that really secures it for me is the Trinity: that amusing, uncanny, and ultimately satisfying play of dynamic and static which we are always looking for. Stubbornly one in substance and essence (such as God is a unity of being-in-itself), but also craftily three in the act of subsistently relating (such as God is a community of love-in-itself): the Lover (Father), the Beloved (Son), and the Love (Spirit).
