What defines repentance unto life?

Repentance unto life is fundamentally understood as a saving grace that encompasses a genuine turning away from sin and a sincere turning towards God. This definition captures the essence of true repentance, as it involves a transformative process where an individual recognizes their sins, feels contrition for them, and actively seeks to change both their behavior and their relationship with God.

This transition is not merely emotional but reflects a profound change in one's heart and mind that leads to a reformation of life according to God's will. The aspect of turning towards God signifies that real repentance is not just about feeling sorry for past actions but is also about seeking a renewed connection with God, emphasizing faith and trust in Him.

In contrast, the other options fail to encapsulate the comprehensive nature of repentance as outlined in the Westminster Shorter Catechism. Merely feeling guilt or acknowledging wrongdoing without the intent to change does not fulfill the requirement of repentance. Similarly, a temporary desire for change without commitment does not align with the biblical concept of repentance, which emphasizes a lasting transformation leading to a new way of living in accordance with God's desires. Thus, the definition provided in the correct choice accurately reflects the biblical and theological understanding of what it means to experience repentance unto life.
