So what do you do at your church? Does your pastor give a sermon, using his words, or do y'all just read the scriptures and that's all? What if your pastor speaks words of encouragement from his heart to your congregation? Wouldn't that be new revelation? If the tongues are interpreted and it is word of encouragement, it's fine, just as if your pastor or anyone in your congregation gave a word of encouragement or motivation to greater holiness in heart and life and evangelism.
