Love isn't a state of perfect caring. It is an active noun like "struggle". To love someone is to strive to accept that person exactly the way he or she is, right here and now.
The ancient hieroglyph for adoration is a gesture of opening that signified both the receipt of divine grace and the offering of the self. When a man or woman stands before God with arms opened wide, the heart is vulnerable to penetration. We allow God to slay us, to kill that which is "other" in us, then to enter and inhabit our form in order for God to know the Divine through us, to resurrect and reconstruct us as changed creatures, as bodies more fully filled with the Light of God.
