Meet our Staff

Rev. Barry M. Foster, Ph.D

Senior Pastor

Rev. Barry M. Foster, Ph.D., started as our Interim Pastor in January of 2019, and accepted the invitation to become our Senior Pastor in August of 2019. Pastor Barry has over twenty years of pastoral experience and was ordained by The International Church of the Foursquare Gospel. Pastor Barry and his wife, Mary, are both graduates of the University of Kansas and loyal Jayhawks. They have been married since 1977, and have four adult children (three married) and seven grandchildren–all of whom, they are grateful to say, love and serve the Lord and his church.

Dr. Barry is also an adjunct professor for The King’s University (Southlake, Texas), teaching undergraduate and graduate online courses in biblical studies, theology, and Christian ministry. He has also taught in church-based ministry schools, led short-term missions trips, and has given seminars and workshops for pastors, ministry leaders, and adults engaged in cross-cultural evangelism and discipleship in both national and international contexts. His doctorate (Trinity Evangelical Divinity School, 1997) is in Theological Studies, with a concentration on exegesis and theology of the New Testament.

My Passion: I long to see the fullness of the kingdom of God realized on the earth, and Jesus rightly honored by the world for who he is and what he has done–to see evil vanquished, suffering ended, the hurting made whole, and righteousness established throughout the earth. To that end, I deeply desire to see the church come to better understand the Bible, to think rightly and deeply about its teachings, to apply its truth more faithfully to our lives, individually and corporately, to grow both in grace and in the knowledge of Christ, to experience and choose to believe the love God has for us, and thus to live as healthy, Spirit-empowered followers of Jesus Christ.

Favorite Scripture: My favorite Scripture is the one I need right now. But I often find special pleasure in remembering Romans 5:1 (“Therefore having been justified by faith, we have peace with God through our Lord Jesus Christ.”) or 2 Corinthians 4:2 (“but we have renounced the things hidden because of shame, not walking in craftiness or adulterating the word of God, but by the manifestation of truth commending ourselves to every man’s conscience in the sight of God.”). Of course, there’s also 3 John 4 which has become very precious to me as I’ve grown older (“I have no greater joy than this, to hear of my children walking in the truth.”). Oh, and . . .

What do you like to do in your spare time? I love being with my family, playing board games, chess, watching sports (cheering for the Royals, Jayhawks, and Broncos) or movies, reading, playing music with friends. I enjoy traveling, skiing, camping, and just being in the mountains. And now that my athletic exploits are mostly an elusive memory of questionable accuracy, I’ve been known to engage in fantasy football.
