What are the effects of regeneration in a believer's life?

The effects of regeneration are profound and life-changing. Regeneration results in a new heart, where the regenerate person now loves Jesus and holiness, while hating the sin they once embraced. As 2 Corinthians 5:17 states, they become a new creation. This transformation impacts their affections, desires, and ultimately their actions, increasingly conforming their lives to the image of Christ. The process of sanctification is fueled by this new life, pointing towards the eternal communion with God that awaits believers.
