“Why is praying in tongues like a Swiss Army knife? A Swiss Army knife is a pocket knife with multiple blades and tools stowed inside its handle. Just as that handle holds many tools, all the operations of the Holy Spirit are inside, or encased in, praying in other tongues, and He pulls out the appropriate tool as it pleases Him (1 Corinthians 12:11). Praying in tongues allows you to develop and increase in your ability to follow His leading. Praying in other tongues is the doorway to the supernatural!”
