Why is repentance important for salvation?

Repentance is fundamentally important in the context of salvation within Reformed theology, as it signifies a true change of heart and mind regarding sin. The story of Zacchaeus provides a clear illustration of this concept. Upon encountering Jesus, Zacchaeus acknowledges his wrongdoings and expresses a desire to make restitution by giving half of his possessions to the poor and repaying those he has defrauded fourfold (Luke 19:8). This demonstrates that genuine repentance involves more than just feeling sorry for one's sins; it requires an active turning away from sin and a commitment to amend one's ways. As articulated in Scripture, true faith is accompanied by repentance, which reveals the transformative work of the Holy Spirit in the believer's life. This aligns with the broader Reformed understanding that while salvation is wholly by grace, it is evidenced by the fruit of repentance and faith, as articulated in James 2:17, stating that faith without works is dead.
