Edification, exhortation, and comfort are received by the saints through prophesying. The prophet edifies the assembly. No one could speak for profit in the assembly unless the mind of God was communicated.
Two things are used by the Spirit, revelation and knowledge. Knowledge teaches truths or explains the Word and supposes a revelation already given of which the speaker availed himself for his own good and that of the saints. The important thing is to make oneself understood, whether singing, teaching or praying.
The speaking with tongues is unprofitable unless there is an interpreter to make the message understood. It is good when the speaker sees nothing in the gift that God has given except what edifies the souls who hear. What a gift to man to be able to impart to others what has been received by revelation or by listening to prophesying.
We cannot be in the presence of God and His Word without our consciences being active. Because of what we are, conscience is needed to lay hold of truth.
Whether in tongues (with an interpreter) or prophesying, two or three were allowed to speak, but one at a time.
Women were to be silent in the assembly and were not to direct others. They were to ask their husbands at home what they did not understand in the assembly meetings.
What the apostle taught was the inspired Word of God, spoken with tenderness and authority. What grace! Those filled with the Spirit would acknowledge that the apostle's words were inspired.
