How do we know conversion is genuine in Christianity?

Genuine conversion is evidenced by a radical transformation in a person's life. It involves a change from a state of sin to one of righteous living, as illustrated in the story of the woman at the well in John 4. After her encounter with Christ, she left her water pot, symbolizing her old life, and became an evangelist. This transformation is foundational in the life of a believer, affirming that true conversion leads to a new passion for God, a hunger for His Word, and a desire to serve Him. Furthermore, the person who is truly converted experiences an inner change, moving from darkness to light, as emphasized in passages such as Ephesians 2:1-10.
