Nathan Lewis

The son of a Jewish father, Nathan Lewis is a husband, father, and pastor with more than two decades of experience shaped by serving the Lord in Scotland and the USA. 

Moving to Edinburgh, Scotland, at 20 years old to study at the University of Edinburgh, Nathan helped start an Every Nation church in the center of the beautiful and secular city. What started as a short-term study program became a life-shaping calling. While completing a master of Arts in Divinity, he answered God’s call to full-time service and, upon graduation, became a pastor. 

As a missionary, Nathan was immersed in apologetics, youth and campus ministry, and cross-cultural mission work. In 2011, he was ordained and installed as the senior pastor of the church, leading it through seasons of growth and outreach, and eventually a transition to indigenous leadership. Nathan’s faith, leadership, and practical ecclesiology developed greatly in this secular, educated environment. Before leaving Scotland, he also earned a postgraduate certificate in Missions in an Urbanizing World from the University of Aberdeen. 

In 2017, Nathan moved to NYC, where he now lives and leads alongside his wife, Ailsa, and three children, Alexander (11), Eden (10), and Ester (4). 

He now serves as a senior pastor at Every Nation NYC, overseeing culture and vision as part of a collaborative preaching and leading team in the undisputed “greatest city in the world.” Nahtan is passionate about seeing the lost found, leaders developed, and new churches started, and has helped support and strengthen church-planting efforts across the Northeastern USA. 

Yosef Koelner Interview

Yosef was raised in an Orthodox Jewish home, then at fourteen years old he was placed in the Foster Care system when his parents passed away. Yosef attended Illinois State University.  He remembers hearing the rock song “Jesus Christ Superstar” and it made an impression on him. A representative of Campus Crusade for Christ came to his dormitory and seeds were sewn.  There came a time when God spoke to him and told him about Yeshua.   He was challenged to read the New Testament.  The next morning there was a box of free books near the mailbox.  He began reading “Good News for Modern Man”  and it all started to make sense.   He met a Methodist minister and began going to his church. Then at 20 years old he became the youth director there.  Yosef still didn’t know that there were other Jewish believers.  He obtained a Masters degree from Messiah Biblical Institute in Washington, DC and another from Gratz College in Philadelphia.  He lived in Israel for a while and teaches Yeshiva courses online.
