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!


Laborers Into the Harvest Field- 2022 Washington DC Prayer Walk! 
April 19, 2022

Hello Friends and Happy Spring-

We pray this finds you well and growing in love. Please enjoy our latest update – feel free to reach out and let us know how we can pray for you. We love and appreciate each one of you!

Dear Friends of the Ministry Center Greetings to all of you and may you daily experience God’s mercy, grace, peace, love and His blessings. I thank God for your prayers, love and support for my ministry and your desire to help build the kingdom of God (Romans 14:17). Here is a summary of what our Lord Jesus Christ is doing through The Ministry Center and the calling of God on my life and ministry. ~God has given me a heart of prayer and intercession, so I spend many hours a day in God’s Word, prayer and meditation. ~Holy Spirit will regularly speak to me and give me words of knowledge, words of wisdom, words of encouragement or affirmation and confirmation for a person or ministry. ~Holy Spirit leads me to give symbolic prophetic gifts to other ministries and individuals. Some of the staffs and gifts are given from me personally and some are given along with other ministries. Following is a list of some of the ministries and individuals that have recently received staffs through The Ministry Center: ~Blessings of Hope ~YWAM- Lancaster ~Living Stones- Dove Newmanstown ~Dove Elizabethtown ~GKH- Attorneys at Law ~Senator Doug Mastriano ~Dutch Sheets- to be given in the near future. ~Teen Central ~Pastors and Friends ~Gateway Church International- York, PA After arriving home from the Northern Cities Prayer Walk in October 2021, I sought the Lord’s heart for my next prayer walking assignment. God placed on my heart to go to Washington DC for a week and prayer walk the city and region. I reached out to Jason Hershey, who stewards David’s Tent, and is involved in the YWAM base in DC. With his input and wisdom, we believe God gave the dates for this assignment from Heaven. God has shown us to pray for laborers and workers to be prepared and sent into God’s harvest field (Mt. 9:36-38; Luke 10:1-3). As Jason and I sought the Lord about the timing of the DC walk, we felt May 6-13 was the right timing and received some confirmations as to the dates as well. The prayer walk will follow the National Day of Prayer on May 5. My prayer walking friend, David Turner, who accompanied me on the Northern Cities Prayer Walk will go with me to DC. We will partner with Jason Hershey and David’s Tent and pray and fellowship with other believers and gatekeepers. It will be a Jubilee week in DC where we will worship, praise, pray, intercede, sing, give thanks, declare and decree the Word and will of God – all in the exalted, magnificent, holy name of our Lord Jesus Christ. Let’s believe together for an outpouring of God’s love, and for His will to be done in our local area and throughout our state and nation! Please check out our website theministrycenteronline.org for updates on our DC trip.

Your prayers and financial support mean so much!

Partnering together with you Calvin and Stephanie Greiner and The Ministry Center Board
