What are the evidences of the new birth?

The new birth is evidenced by several fruits in a believer's life. 1 John 3:14 highlights that a genuine sign of having passed from death to life is love for the brethren. Other evidences include a change in understanding and attitude toward sin, a demonstrated faith in Jesus Christ, and the perseverance in faith produced by the Holy Spirit. These signs affirm the legitimacy of one's claim of being born again and testify to the transformative power of God's grace at work in their lives.
