You are an agnostic.
‘There may or may not be a God, I don't know; and I'm not convinced that anyone can know for sure.’
The claim that, ‘we cannot know’ is based on an assumption that an idea cannot be verified or held with integrity unless I’m able to work it out using my standards of logic or scientific methods. If we all only ever lived that way, there would be no such thing as beauty, creativity, humour, joy or love. In fact, to rule out the possibility of knowing something for sure I need to be just as dogmatic as those who claim to know!
If I’m an agnostic, I also assume that God - if he exists - has not done enough to make himself clearly known to me - I assume that the fault isn't with my ability or willingness to know, but with God’s ability or willingness to make himself known. What if our ignorance is actually a refusal to believe? What if you don’t want to know, because you're not sure if you can handle the truth?
Knowing God does not depend on us, but on God who makes himself known - and He has!
’...what can be known about God is plain to us, because God has shown it to us. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So we are without excuse.'
(Paul, writing to Roman Christians, 1:19-20)
‘Whoever has seen me has seen the Father’ (Jesus in John 14:9)
