Reformed Evangelism: Interview with Ryan Denton

In this episode of the Unashamed Truth Podcast, Grant Castleberry is joined by evangelist Ryan Denton for a rich and practical conversation on evangelism, Reformed theology, and the Christian life. Ryan shares his powerful testimony of conversion and how the Lord led him into open-air preaching on college campuses and in public spaces across the country. Together, they address a common misconception—that Reformed theology hinders evangelism—and instead show how the sovereignty of God fuels bold, confident gospel proclamation.

This episode is both theological and deeply practical. You’ll hear:

  • Why evangelism is essential for every believer

  • How to overcome fear when sharing the gospel

  • What open-air preaching looks like in real life

  • How churches can cultivate a culture of evangelism

  • Practical tools like gospel tracts and conversations that lead to Christ

Whether you’re new to evangelism or looking to grow in boldness and clarity, this conversation will encourage you to trust God, proclaim Christ, and leave the results in His hands. Subscribe for more content that equips you to stand with biblical clarity and bold conviction.
