How do we know the doctrine of turning from sin is true?

The truth of the doctrine regarding turning from sin is corroborated by several scriptural references. In Acts 3:26, it states clearly that Christ was sent to bless us by turning each one from their iniquities. This aspect of salvation is essential since sin constitutes a barrier between humanity and God. Furthermore, scriptures such as 1 John 1:9 affirm that if we confess our sins, He is faithful to forgive us and cleanse us from all unrighteousness, thus implying a transformation. Moreover, Romans 8:1-2 emphasizes that through Christ, we are freed from the law of sin and death, further validating that the power of sin can indeed be overcome through Him, establishing the doctrine as true and essential to the Christian faith.
