To make a decision to turn away from sin and darkness, from the power of the devil to the living God. We repent from our former sins, cast off our old life – a life which enjoyed living in the passing pleasures of sin – and lay hold of a new mind – a mindset that is determined to resist sin (say “No!” in temptation). It is also important, after conversion, not to return to the environment which had a negative influence on one before conversion, otherwise things can go badly again. (Acts 3:19; Acts 26:18; Ephesians 4:22-24; 1 Peter 2:1-2)
