Charting my theological beliefs must begin with my most basic presupposition: God is.
I could also say “God exists,” but I find “God is” to be a nice reflection of Exodus 3:14, where God reveals himself to Moses as “I AM.” French philosopher Descartes could only get as far as “I think, therefore I am.” God simply declares “I AM” without any qualifiers or adverbs!
As of 2010, according to the CIA World Factbook (!), only an estimated 9.66% of the world’s population were non-religious and only 2.01% were identified atheists. The vast majority of humans believe in some form of higher power or powers and so do I. My unbelieving friends believe that I believe. However, I would claim that I don’t just believe, but that I know that God exists. And this basic fact underlies all of reality.
Logically or semantically, you cannot know something that isn’t true. Although I initially believed in God because of the testimony of reliable people in my life, I came to know this experientially as God revealed himself to me. I have encountered God and am growing to know God more over time as our relationship continues. As Jesus is quoted in John 10:27, “My sheep hear my voice…”
I have known my oldest childhood friend since preschool. Nobody could convince me that he doesn’t exist. There is not an argument on earth that could erase from my mind the unmistakable relationship we have experienced. However, it would conceivably be possible for someone to show me a birth certificate or other information that revealed that the person I thought I knew so well was really somebody else entirely – that he had been misrepresented or had been misrepresenting himself this entire time. Likewise, I believe that individuals can experience supernatural encounters / phenomena but not necessarily arrive at accurate conclusions.
English theologian John Hick (1977, 7) talks about “simple verifiability” versus “complex verifiability.” If I want to verify that there are three apples in a basket, all I have to do is go over, look, and count them. Other things are not so easy, such as large-scale scientific hypotheses. I cannot walk over to the universe and check if Superstring Theory is true. “In such cases there may be increasing confirmation until the point of cognitive conclusiveness is reached. This is the point at which rational doubt as to the truth of p has been entirely excluded and at which the concepts of confirmation and verification coincide.”
Does a single observation suffice? Is progressive experience required? Is there a tipping point where uncertainty becomes belief, and belief becomes knowledge? I can state that I am subjectively certain that “God is.” I believe that one day this will be an objective, empirical certainty… that “every eye will see him” (Revelation 1:7).
But to quote C.S. Lewis, “I am not yet within a hundred miles of the God of Christian theology.”
