How do we know the importance of conscience in a Christian's life?

A well-formed conscience is crucial for Christians, as it reflects God's moral order and provides guidance in making decisions aligned with His will. In the context of Herod's actions, we see how a troubled conscience can lead one to engage in destructive behaviors in an attempt to silence the inner voice of guilt. The Bible reminds us that no matter how loud the external pleasures of the world become, the unease of the conscience remains, revealing the need for atonement and reconciliation with God. Romans 2:15 speaks to how our consciences bear witness, either accusing or defending us, emphasizing the necessity for believers to heed its promptings toward righteousness and away from sin.
