God is spirt and we are created in His image. We crave the supernatural. There is no limit to where we can go in the realm of the spirit.
Do I have to speak in tongues? Tongues is the evidence of this experience. We can have measures of power on us for the purpose of witnessing. Praying in tongues is praying back His purpose and then He fixes His mind on us and builds His presence. He can enlarge Himself which will magnify God and His plans/purposes above your circumstances. We are commanded to speak in tongues. The Holy Spirit is the plug for the power. Speaking in tongues keeps us connected to the Power Source!
