Yeah that's right, we all need to SHUT OUR OPEN MINDS...on something solid. There is a great temptation and danger in our postmodern context to so overvalue the journey towards God and truth that all we ever do is have a conversation. Absolute truth exists, we may never have exhaustive knowledge of that truth, but we can and must have certain knowledge: that God exists, that forgiveness of sing come only through Jesus Christ, that the Bible is God's authoritative revelation of Himself to us.
I found this quote by G.K. Chesterton both winsome and convincing:
"The object of opening the mind, as of opening the mouth, is to shut it again on something solid." (Autobiography. Collected Works Vol. 16, p. 212)
