How do we know that eternal life begins at regeneration?

The concept of eternal life commencing at regeneration is supported by John 11:25-26, where Jesus states that those who live and believe in Him shall never experience death. This reflects the transformative work of the Holy Spirit, granting life to the spiritually dead through the proclamation of the Gospel. Regeneration is the divine act of creating life where there was none, allowing individuals to respond in faith to Christ. The life given at regeneration is the same life that believers will enjoy in heaven, which is everlasting and rooted in the person and work of Jesus Christ.
