Jacob Warren
Pastor of Congregational Life

As Pastor of Congregational Life at New Covenant Church, Jacob’s overarching desire is that he himself might know the love of Christ more deeply and that he might be a part of the work “to equip the saints for the work of ministry, for [the] building up the body of Christ, until we all attain to the unity of the faith and of the knowledge of the Son of God, to [maturity], to the measure of the stature of the fullness of Christ.”

 Jacob completed his undergraduate degree at East Texas Baptist University in 2001, where he met and married his best friend Sara. After graduation, he and Sara moved overseas where they sought to serve Christ via cross-cultural ministry. It was during this time that all three of their children were all born as foreigners abroad. After returning to the States, Jacob completed his seminary degree while working full-time in the banking industry. Jacob then served as a corporate chaplain for two and a half years before joining the two-year pastoral residency program at College Church. Jacob and his family are excited about this new role at New Covenant Church and are desirous of your prayers!
Greg Wheatley
Director of Music

Greg Wheatley says that some of his earliest memories of music were of learning to play the piano under the instruction of his grandmother. From that point on, he can’t remember a time when there wasn’t music of some kind in his life. After graduating from high school, he attended Spring Arbor College, where he earned a degree in music. He eventually went on to earn a Master’s degree in music theory from Michigan State University. Along the way, Greg’s involvement in Christian broadcasting brought him to Moody Radio, where he spent 22 years. His interest in broadcasting combined with his love of sacred music resulted in the program Sound of Majesty, which aired on Moody Radio for most of those 22 years.

Greg has considerable experience in choral conducting. He is the musical director of the Glen Ellyn-Wheaton Chorale. He has also served as the director of the College Church Singers and as one of the interim directors of music at College Church. He serves on the adjunct faculty at Wheaton College.
