How do we know regeneration by the gospel is true?

Regeneration by the gospel is shown to be true through its grounding in Scripture, such as Romans 1:16, which states that the gospel is the power of God for salvation to all who believe. This transformative power of the gospel has been affirmed throughout church history, where countless individuals have experienced profound life changes upon receiving the word of truth.

Moreover, examples abound in Scripture where people have been transformed from spiritual death to life through the proclamation and acceptance of the gospel. Acts 2 recounts the dramatic conversion of thousands at Pentecost when Peter preached. Such historical and biblical evidence reinforces the doctrinal truth that regeneration is not only a theological concept but a practical reality evidenced by changed lives.
