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.

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.
