1. For the strengthening of the church (26-28)
Apparently when the church in Corinth met for worship, there was much noise and confusion. The atmosphere did not encourage spiritual growth; God was not really worshiped. Singing hymns and praying and expounding the word of God should all be a part of the worship service, but these things should be done in an orderly way. This will please God and build up believers.
2. In a fitting and orderly way (29-40)
Prophets are Bible teachers. When one speaks God's word in the congregation, everyone should listen carefully and weigh what is said against the Bible. Those who have something to say from God should speak in turn. The women had a tendency to to talk and not listen. If they had questions or wanted to gossip or talk about something other than a revelation from God, they should do it at home. The worship service is a time to worship God.
Application: Lord, help us to make an environment in our worship service in which your Spirit can work, and in which we can worship you in spirit and in truth.
One Word: Worship God and grow in faith
