Let me suggest to you that holiness is not what you think it is. In theological terms we talk about holiness as being ‘set apart’—set apart for God. Even that, however, is a misunderstanding of the word. The actual root word is hool with “w” placed at the beginning, and it literally means whole. The simple duty of us all becomes nothing more, nothing less than becoming whole. Holiness is the process by which we integrate the loose threads of our life into a whole tapestry of beauty and divine grace. This is a creative task for the entirety of our lives. The good news is that we can set aside all the to-do lists of things that we think are required for reaching some standard of moral and spiritual perfection, and open ourselves instead to the invitation and creative possibility of becoming whole in God.
To become whole in God means aligning our lives with God through such things as seeing the world and ourselves through God’s eyes; forgiving others even when the pain of hurt and betrayal sticks in the throat like hard, dry clay; not judging others even when their behavior makes our heartbeat quicken and our breath shorten; having the courage to face evil and overcome its power with the goodness that is foolhardy in the eyes of the world; staying in the place of unconditional love even when love seems imprudent and so difficult as to make us want to run away.

Understanding holiness is one of the central elements of the Christian life. Far too often we see it as some lofty, unattainable, almost gnostic ideal rather than grounding it in reality. If we can first ground holiness in reality we may find it easier to open our lives to God’s work in us towards it.
