Their names are written in your book

now let them also be written on our hearts

This prayer was hidden in the journal of one of my favorite evangelists, a man who at the peak of his ministry was estimated to have personally preached to 80% of the United States during the First Great Awakening.

This same man preached in Annapolis to little avail, later commenting in the same journal that it was the most spiritually dark place he had ever visited.

I’m Aaron Rosa

a former Naval Officer turned local missionary, evangelist, and storyteller. I graduated from the U.S. Naval Academy in 2011, spent years flying for the Navy and then took a different kind of mission—one that led me into the streets, the church, and the stories people carry.

Along the way, I earned a master’s in journalism from the University of Maryland and worked as a news photographer, capturing moments that mattered. But eventually, I found myself more drawn to the deeper narratives beneath the headlines—the ones about brokenness, redemption, and the God who meets us there. That pull led me to Westminster Theological Seminary, where I deepened my understanding of the Gospel and its implications for the world around me.

Now, through my work with Estuary, I move between churches and communities, bridging the gap between scripture and everyday life. I believe evangelism isn’t just an activity but the natural outflow of truly grasping the Gospel. Jesus goes where people are, and that’s where I go too—whether it’s through preaching, teaching, writing, or just showing up in the places where the Gospel is least expected but most needed.
