What is the surest character of true, divine, supernatural love that distinguishes it from counterfeits that arise from a natural self-love? It is the Christian virtue of humility that shines in it. Divine love above all others renounces and abases what we term “self.” Christian love or true love is a humble love… In that person we see a sense of his own smallness, vileness, weakness, and utter insufficiency. We see a lack of self-confidence. We see self-emptiness, self-denial, and poverty of spirit. These are the manifest tokens of the Spirit of God.
Jonathan Edwards
