Church meetings are to be conducted by the inspiration of the Spirit.
9 And their meetings were conducted by the church after the manner of the workings of the Spirit, and by the power of the Holy Ghost; for as the power of the Holy Ghost led them whether to preach, or to exhort, or to pray, or to supplicate, or to sing, even so it was done.
Elder Bruce R. McConkie said:
“We come together in congregations, seeking the guidance of the Holy Spirit, studying the revelations, reading the scriptures, and hearing expressions of doctrine and counsel given by those who are appointed. These teachings ought to be delivered by the power of the Holy Spirit. They ought to be received by the same power. And if they are, then the speaker and the hearer will be mutually edified, and we will have true and proper worship.
“Then when the meeting is over, the ‘amen’ should not end it. We should go to our homes and to our families and to our circles, and we should search out the revelations and find out what the Lord has said on the subjects involved. We should seek to get in tune with the Holy Spirit and to gain a witness, not solely of the truth and divinity of the work in which we are engaged but also of the doctrines that are taught by those who preach to us. We come into these congregations and sometimes a speaker brings a jug of living water that has in it many gallons. And when he pours it out on the congregation, all the members have brought is a single cup and so that’s all they take away. Or maybe they have their hands over the cups, and they don’t get anything to speak of.
“On other occasions we have meetings where the speaker comes and all he brings is a little cup of eternal truth, and the members of the congregation come with a large jug, and all they get in their jugs is the little dribble that came from a man who should have known better and who should have prepared himself and talked from the revelations and spoken by the power of the Holy Spirit. We are obligated in the Church to speak by the power of the Spirit. We are commanded to treasure up the words of light and truth and then give forth the portion that is appropriate and needful on every occasion.”
