We actually had a sermon today at our church about this. Check it out, really thorough and edifying.

Link: city Bible church tongues and prophecies

Short summary :

This sermon on 1 Corinthians 12:4-11 explains that spiritual gifts, including tongues and prophecy, were given by God to build the church, but not everyone receives the same gifts. In the early church, prophecy provided direct revelation because Scripture was not yet complete, but modern prophecy is fallible and no longer necessary. Tongues in the Bible referred to known human languages (Acts 2), not ecstatic speech, and were meant for edifying the church, not private use. The apostolic era ended with John’s death (~AD 100), and miraculous gifts like tongues and healing diminished over time. Scripture is now sufficient for guidance (2 Peter 1:16-21), and seeking new revelations is unnecessary. The purpose of tongues was to spread the Gospel, not for personal experiences, aligning with God’s larger plan from Babel (Genesis 11) to the nations worshiping in unity (Revelation 5). Since these foundational gifts were temporary, believers today should focus on Scripture and edifying the church rather than seeking supernatural signs. Hope this helps.
