* It is a popular practice in many christian ministries to exploit a preacher's ministry by not blessing him financially. The anointing of the Holy Spirit cannot rest on such a house if that church/ministry 'muzzle the ox that treads the grain'. (See 1 Tim 5:18, Gal 6:6)
Consider if it is the right time to bring in a guest minister. If so the local church leadership should budget for such an event.
Additionally, there are no guarantees that Prophet Carter will lift an offering on the church's asking. Note, HE WILL NOT PROPHESY TO INDIVIDUALS IN EXCHANGE FOR MONEY (Jude 1:11). He must be led to do personal and corporate prophecies (2 Peter 1:21).
