The law and commandments was a ministry of condemnation. Christian ministers who emphasize the power of sin are ministering condemnation. Such ministry does produce results.

However, the real power of the Gospel is in the fact that Christ Jesus -> has covered all sin by His own blood, -> has imputed His righteousness to us by faith and -> has filled us with His HolySpirit.

The power of sin is miniscule compared to the unlimited power of a transformed life.
