Ministry is about leading people, influencing them to become the most they can be in Christ.
Ministry is also about serving people, thinking of others as more important than yourself while also doing the work of setting up and tearing down tables and chairs.
Sometimes a church internship can end up being all about completing tasks–tables and chairs. Often times they miss the opportunity to mentor you to be what God desires you to be. Others just let you sit around for a couple months, waiting to be done with a school requirement.
