Hello and welcome to The Ministry Center website! Here you will find the amazing mandate that the Lord Jesus gave to Calvin Greiner in 1993; be encouraged as you uncover the foundation of TMC (relationships, intimacy, giving glory to God, holiness and trust); and follow Calvin as he walks throughout the land declaring the salvation of the Lord and restoration of all things through prayer.

  Our prayer is that you will be challenged to fulfill your God-given destiny, inspired to believe God for the impossible, and partner with us as we seek to serve the Body of Christ through prayer and encouragement and connect each member of His Church throughout the US and the world!
