How do we know that sanctification is part of the believer's life?

Sanctification, or the process of being made holy, is integral to a believer's life as a direct result of justification by faith in Christ. This transformative work is highlighted in Ephesians 5, where believers are urged to walk in love and righteousness as a reflection of their new nature. The evidence of sanctification is displayed in the believer's growing desire to obey God's commands and to live a life that is pleasing to Him. The Holy Spirit's work empowers believers to turn away from sin and pursue holiness, showcasing the dynamic relationship between faith and works in the life of a genuine believer.
