What becomes the disposition of the soul following the new birth?

The correct answer is holiness. Following the new birth, which is a transformative spiritual experience often referred to as being "born again," individuals are believed to receive a new nature that reflects the character of Christ. This transformation is foundational to the Christian faith, emphasizing that a person who has experienced the new birth is called to live a life marked by holiness.

Holiness is the state of being separate from sin and dedicated to God. It embodies the idea of an inner change that results in outward actions and attitudes aligning with God's will. The new birth signifies not just a decision but an inward renewal that results in a desire to pursue righteousness and live in a way that honors God.

In the context of Christian teaching, while love, faith, and joy are indeed fruits of the Holy Spirit and important aspects of a believer's life, the specific disposition that arises as a result of the new birth is fundamentally tied to holiness. This reflects the understanding that with new life in Christ comes a call to be set apart for His purposes, thereby striving toward holiness.
