Is it possible to be a theist and an agnostic at the same time? I see religion as very important for providing a firm foundation for morality, I also do see evidence for a supernatural, numinous (to use a term from Rudolf Otto) or Unseen (to use a term from Mike Heiser) realm, largely due to what I have heard from my relatives. I frequently pray to God, presupposing that he exists.
But I have yet to see any firm, conclusive evidence that God actually exists. Which is why I consider myself to be an agnostic, in spite of my faith in God. That and the fact that it is most rational for everyone to accept the chance that they could be wrong, which is why I have always said that everyone, atheist or theist should be an agnostic.
