Tongues are spiritual codes. It's like sofas. It may not make sense to your physical ear while we pray it, but it is producing statements in the spiritual realm. There are ways you speak in tongues and become use to it, the Holy Spirit will teach you how to combine those codes (i.e. dada and ratata, brakata 🔥), like a sofa and make it a decree in the spirit realm. Listen to this podcast by God's servant - Apostle Alfred, and you will start speaking in tongues immediately.
