Jesus did not seem to teach that one size fits all, but instead that his God adjusts to the vagaries and failures of the moment. This ability to adjust to human disorder and failure is named God's providence or compassion. Every time God forgives us, God is saying that God's own rules do not matter as much as the relationship that God wants to create with us. Just the Biblical notion of absolute forgiveness, once experienced, should be enough to make us trust and seek and love God.
