What does the Bible teach about a converted heart?

Scripture indicates that a converted heart is fundamentally transformed and now aligned with God’s will. This transformation is often described as being 'born again' (John 3:3), where one is brought from spiritual death into life through faith in Jesus Christ. A converted heart produces good fruit as a natural outcome of being grafted into Christ, the true vine (John 15:5). Consequently, believers exhibit the fruit of the Spirit in their lives, not through their own strength, but due to the work of the Holy Spirit within them (Galatians 5:22-23). As a result, understanding this transformation encourages believers to rest in Christ’s finished work, nurturing a life that bears witness to His grace and love, reflecting the character of Christ to the world.
