"God doesn’t use perfect pictures; He uses broken people." - Pastor Carl

As a 25-year resident of Citrus County, Carl has learned to love life in a small town. He and his wife, Megan, have been ministering to youth and families for the past 16 years. Making an eternal impact has been their driving passion. That passion led them to Lakeland, Florida, where Carl obtained a Bachelor’s Degree in Business from Southeastern University. After graduating, Carl and his family spent three years on the mission field serving the needs of vulnerable and orphaned children in Africa. His time on the mission field and here at home has taught Carl that life should not be lived alone; there is joy and power in community. As our Children’s Pastor, Carl’s greatest joy is to see families grow closer to God and each other. He was licensed as an Assemblies of God minister in July 2017.

While there, he launched his ministry called, Impact Volume Ministries, which is now known as Corey Ball Ministries. He has traveled the world, preaching the Gospel ever since.

Mackenzie has been running the halls of Calvary Church since she was almost two years old and has always felt the call of God on her life to be a worship leader. She has been leading worship since age 11 in the student ministry when her father, Pastor Ottis, was Student Pastor. In 2017, she moved to Hamilton, AL, to attend the Ramp School of Ministry. During her time there, she was equipped in their worship department and got to travel and minister across the country with Chosen and also Corey Ball Ministries. While in Alabama, she met and married Corey Ball. In December 2020, they welcomed their first-born daughter, Harvest Ball. Mackenzie is passionate about worship and leading God’s people into His presence now more than ever.

Nothing is more important to her than creating an environment where the Holy Spirit can move.
