(1Co 14:30) “If any thing be revealed to another that sitteth by, let the first hold his peace. (31) For ye may all prophesy one by one, that all may learn, and all may be comforted.” I remind you, in our services, it is not about you. It is about the Lord. Those serving should have such humility that if they do not get to speak, or sing, or do whatever it is they were prepared to do, it is humbly accepted.If they cannot do so, they have no business serving.
