“Pursue love, and earnestly desire the spiritual gifts, especially that you may prophesy” (v1). The Corinthians were apparently enamored with speaking in tongues, to the point that their gatherings were disorderly and unedifying. Paul explained that “when you come together” (v26), it should be for the purpose of mutual “upbuilding and encouragement and consolation” (v3). Speaking in tongues publicly, therefore, should be interpreted, so that everyone can understand. Others might offer “a hymn, a lesson, a revelation” (v26) etc. Gathering together is a time for the focus to be on worshipping God and building up one another.
God gives us gifts so that His Spirit can move among us, “so that all may learn and all be encouraged” (v31).
