How do we know the blood of Christ clears our conscience?

Scripture assures us that the blood of Christ effectively purges our conscience from dead works to serve the living God. Hebrews 9:14 emphasizes that the blood He offered, without spot, through the eternal Spirit, is sufficient to cleanse our hearts. This is foundational to the Reformed understanding of salvation, where the sacrificial death of Jesus is the sole remedy for our sinfulness, enabling us to approach God with a clean conscience. It is through this cleansing that we can live honestly before Him and acknowledge our continual need for His grace.
