1 Corinthians 14.  All of the problems that Paul was dealing with here have to do with speaking in church. He identifies three specific problems:
1) too many people were “speaking in tongues” instead of prophesying;
2) too many people were speaking all at once, which was leading to confusion;
3) some of the women of the congregation were speaking, and, for some reason that too was causing disorder.

In verse 12, Paul encourages the Corinthians to keep striving to excel in building up the church. That is the BIG IDEA that Paul is trying to get across in chapters 12-14. May we never forget that. We need to constantly evaluate ourselves to see if the things we are doing when we meet together are actually building up the body. If First century Corinth could have problems – even after being founded by Paul himself – then we have no reason to assume that the 21st century church is immune.

LORD, before we say anything in church, help us to ask ourselves “will this help the people who hear it?” If it will not help, give us the consideration and love to keep our mouths shut!” Amen.
