This text, like all Scripture, should be read in context. If you tug on 1 Corinthians 13, you quickly find that it is tethered to the rest of the epistle and resists being torn from it. This isn’t rocket-surgery, but 1 Corinthians 13 comes between 1 Corinthians 12 and 1 Corinthians 14. There is a reason Paul includes this here. Paul has begun a discussion about spiritual gifts in chapter 12. He has written that the body of Christ is composed of many members with different functions, and that every member’s role (no matter how big or small it seems) is indispensable. The hand can’t get rid of the foot and expect to be productive, and the eye can’t make its exit from the body and hope to have any use except for disturbing Halloween pranks. The Spirit has distributed these tasks throughout the church and has equipped every believer with abilities to serve the people of Christ. And then, in chapter 14, Paul wants to put forward a principle that will determine how the church operates in spiritual gifts, particularly with prophecy and tongues. That principle is that everything must be done in the gathered church in order to build up others. This is the idea he repeatedly presents in chapter 14.
