In the book Transforming Spirituality: Integrating Theology and Psychology theologian F. Leron Shults writes:
The justice (or law) of God is fulfilled by love, as both Jesus and Paul insist (Matt. 22:36-40; cf. Mark 12:28-34; Rom. 13:8-10; Gal. 5;14; cf. James 2:8). Becoming just therefore involves becoming an agent who manifests love. Finite agents do not have the power to fulfill this law of love, and so becoming just ultimately depends on the grace of God, who calls us to share in divine love by following in the way of Christ in the power of the Spirit. Our moral desire is only conformed to Jesus’ way of relating to the Good as we “die to sin” and are “crucified” to the world, no longer relying on our own power to secure the objects of our desire but actively resting in the omnipotent consoling agency of absolute Love. There are no shortcuts to developing a virtuous disposition; it requires the painful process of introspection and working out one’s redemptive agency in community. This too occurs by the gracious agency of the Holy Spirit as Christ is formed in us (cf. Gal. 4:19).
