What does the Bible say about repentance and faith?

Acts 20:21 emphasizes the necessity of both repentance toward God and faith in our Lord Jesus Christ. This passage highlights the transformative order of spiritual operations—regeneration must precede sanctification. An unrenewed heart cannot pursue holiness as it is devoid of spiritual life. Therefore, the first step for a person is genuine repentance and a recognition of their sin, leading them to seek life, pardon, and acceptance through faith in Jesus. Both elements are crucial for a true relationship with God, as without this faith, efforts towards holiness are futile.
