Acts 2:4 And they were all filled with the Holy Spirit and began to speak in other tongues as the Spirit gave them utterance.
The first reason every believer should speak in tongues is because tongues are a restoration of divine communication with God. First Corinthians 14:2 (NASB) says, “For one who speaks in a tongue does not speak to men but to God; for no one understands, but in his spirit he speaks mysteries.” When man was first created, he had something wonderful that he unfortunately lost in the garden of Eden: he had a tremendous fellowship with God. He could walk with God in the garden and could talk to Him as a friend, face to face. But Adam and Eve fell out of fellowship with God and a wall of separation came between them. That divine communication between man and God was severed. When you are born again, that relationship with God is rekindled. When you are baptized with the Holy Spirit, you are given the ability to communicate with God in an intimate way. You receive a prayer language and the lines of communication between you and God are opened. Deep divine communication is restored. First Corinthians 14:14 (NKJV) says, “For if I pray in a tongue, my spirit prays.” This means that it is not my mind praying, but my spirit, the deepest part of who you are. Those times when you are praying in tongues, your spirit is praying, rather than your mind. This is important because our minds, our own natural thoughts, are one of the biggest problems in communicating with God. Our thoughts tend to separate us from the thoughts and plans of God. When you pray in tongues your spirit prays God’s thoughts and God’s plans. When you are praying in tongues, you are connected to God and are expressing yourself to Him out of the deep recesses of your spirit. First Corinthians 14:15 (NASB) reminds us not to ignore our natural language, however: “What is the outcome then? I will pray with the spirit and I will pray with the mind also; I will sing with the spirit and I will sing with the mind also.” Both your prayer language and natural language are vital in communicating with God. As we spend time praying in our heavenly language, we become more aware of the spiritual realm. Every day we spend a large amount of time doing just natural things, but when we begin to yield to the Lord and pray in the Spirit, the things of earth grow dim and the heavenly world becomes alive to us. Jesus becomes comes real to us; the heavenly Father becomes real to us, the kingdom of God becomes very real to us. We begin to experience the intimacy that we were created to enjoy. This enjoyment of the heavenly world becomes stronger as we grow in the things of the Spirit. Pray with the Spirit and with your understanding and enjoy this restoration of intimacy with God.
