John began his ministry with Harvest USA as a volunteer while in seminary.  As Founder of the organization he champions the mission of Harvest USA.  He has a deep burden to see those who struggle with their sexuality, with pornography, or with sexual addictions to experience the truth and mercy of the gospel through Jesus Christ in order to live godly and faithful lives. John spends most of his time helping churches be equipped to better care for the hearts of individuals and families vulnerable to these struggles.
