Although you’ll need to deal with what Paul is talking about here as he deals with the issue of tongues and prophecy, Paul’s primary concern here is not about answering all our questions about tongues and prophecy and instead is about the benefits of each of those gifts. In short Paul’s argument is that prophecy is a more desirable gift because it benefits the hearer while tongues benefit only the one speaking in tongues.
We learn a few things from this:
1. The word of God is incredibly important for the building up of the church.
2. The purpose of corporate worship services should be the building up of all believers not merely self-fulfillment.
