Gavin is a fellow of The Keller Center for Cultural Apologetics, a fellow of The Center for Baptist Renewal, a fellow of Credo, a member of St. Basil Fellowship of The Center for Pastor Theologians, and a Visiting Scholar at Reasons to Believe. He regularly speaks at churches and conferences around the country.

Gavin runs the YouTube channel Truth Unites, which seeks to promote gospel assurance through theological depth. Truth Unites has a dual purpose as both a theological resource to the church as well as an apologetics voice to our culture. In its inward-facing role, it seeks to serve the church with theological education. It especially focuses on historical retrieval and theological triage, seeking to buttress and unify evangelical theology amidst its current fragmentation. It also produces content in defense of Protestantism. In its outward-facing role, Truth Unites seeks to provide a winsome and credible voice to the culture for the existence of God and the resurrection of Christ.
