Senior Pastor

Rev. Joshua M. Knott

Joshua counts it a great joy and privilege to have been raised in a Christian home.  He made a profession of faith when he was young and gradually came to understand both the depths of his sin and the sufficiency and beauty of his Savior.  Around the same time the gospel 'came alive' he was drawn to the Word of God and to anyone he could share it with.  Sensing a call to ministry throughout his youth, Joshua pursued a Biblical studies major and Philosophy minor at Grove City College (B.A., 2001), and, after marrying his high school sweetheart, did his graduate work at Reformed Theological Seminary (M.Div., 2004).  After serving 11 years as an Assistant and then Associate Pastor in Newark, Delaware, the Lord called Joshua and his family to Cornerstone in August of 2017.

Assistant Pastor

Rev. Tim Burden


Tim comes to Cornerstone with a heart for adult discipleship and small groups, as well as degrees from Liberty and Covenant Seminary. At Covenant he interned at the Francis Schaeffer institute and, later, at Grace and Peace Fellowship. After serving as an Assistant Pastor at Peace Presbyterian in Cary, NC, he became Senior Pastor at Eau Claire Presbyterian Church where he served for four years. Tim joined us with his daughter in March of 2019.

Music Director

Rebekah Fry has participated in and helped led God's people in worship for most of her life.  She is currently finishing her Masters in Piano Pedagogy at USC while teaching piano to many students and leading our praise, choral, and instrumental groups at Cornerstone church.  

Children's Director

Mrs. Debbie Wenger

The daughter of missionary parents to Zimbabwe, Debbie grew up during a ten-year long civil war in that nation.  Such a childhood gave her many opportunities to see that God answers prayer and is at work today just as much as He has ever been.  Moving to the US in 1987 to go to college at Columbia Bible College (now CIU), she graduated with a BS in Elementary Education and an M.A. in TEFL (Teaching English as a Foreign Language) before marrying her husband, Mark

Debbie loves opening the Word of God with others, particularly children and young teens, and has used her training and her gifts in these capacities in every place she and her family have served: first at Cornerstone, while raising support to go out as trainers of cross-cultural workers in South Korea, then as a mother and teacher of her own children and those of others in her home, neighborhood, and then again at Cornerstone.  Rather than going out as career trainers of cross-cultural witnesses of the Gospel, the Wengers found God calling them to stay in Lexington, SC, where Debbie has continued to serve in the church as a teacher and volunteer throughout the past eighteen years. 

In 2016, God moved her husband out of the work he had been doing and back into cross-cultural work, as administrator of an organization sharing the Love of Christ where He is least known.  Prior to that change in Mark’s employment, however, Debbie had already stepped into interim leadership of the children’s ministry at Cornerstone.  She continues to delight in helping children and the adults and youth working with them, fall more in love with God by creatively attending to His Word, prayer, and worship.

Jimmy was born in Richmond, Virginia. He attended Columbia International University where he majored in Bible and Youth Ministry. He also did further studies in counseling. He began working at the college as a video producer, where he remained 4 years until heading into full-time youth ministry.

He was the video producer at a church of 15,000, helping them establish video support for the services. After building a solid core volunteer staff, he went back into youth ministry in his hometown. In all, Jimmy spent nearly 20 years in youth ministry and several years in Church planting. He has always had a love for media as an open door for truth, and has been a photographer and designer for much of his life. His daughters Sophie and Kinsey both love Christ. They have traveled tens of thousands of miles together over the years and enjoy the adventure.  Jimmy currently writes a weekly faith column for a newspaper in Tennessee. His passion is communicating truth and finding creative ways to spark people's interest in following Christ.
