What does Scripture say about the role of conscience in religion?

According to Romans 2:14-16, conscience serves as a witness, either accusing or excusing individuals based on their actions. However, relying on one's conscience alone leads to self-justification and an inability to recognize true sinfulness before God. This is evident throughout the narrative of humanity, where individuals often look to their conscience to determine their moral standing, falsely believing they can justify themselves. Therefore, while conscience plays a role in identifying guilt, it does not offer the means for redemption; only the Gospel of Christ can effect true change and lead one to salvation.
