This kind of union with God is never the purpose of spiritual life in the Bible. This is of fundamental importance as we consider what spirituality is. The emphasis on the total otherness of God leads to a devaluation of all language and of knowledge perceived by the mind.
Language is considered to be essentially idolatrous.
We have shown elsewhere that language is not idolatrous because there is a correlation between God and man. The confusion here arises from forgetting the distinction between true knowledge and exhaustive knowledge, true language and exhaustive language. In saying we can know or say certain things about God, we do not claim that we have said everything about God which can be said, or that we know all that can be known. This is true not only of our knowledge of God but even of our knowledge of other people or of the material world. Though incomplete, our knowledge of God is accurate because he has made himself known to us in the Bible and there described himself for us.
