Holiness cannot be divorced from love. Here love and holiness are dealt with as two sides of one coin. The God if the prophets is the Lover of all men who will not simply stand by while people make pigs of themselves. He is the Holy One of Israel. When the prophets call the people to trust in God, they are asking for a loving response to the God who, on love, has committed Himself to them.
Faith is love trusting.
Obedience is love doing what it is told. Prayer is love on its knees. Peace is love enjoying harmony in relationships. Forgiving is love tearing down walls. Patience is love doing it over and over again.
