Knowing and not knowing

St John said that we know that we have passed from death to life but St Paul said that we only know in part. To know is not to know all. We can know enough to be able to live and move and have our being, physically and spiritually. But we should also know that there is much that we don't know. It is said that faith is a balance of knowing and not knowing. We may find satisfaction in knowing but humility in realizing that there is much that we cannot know or, in other words, mystery in life and death.
