Fear can paralyze, demoralize, and even kill. Fear can cause someone to keep silent when he should speak up. Fear spawns hatred, bigotry, hostility, and conflict. We need to breathe the clean, pure air of the Holy Spirit, and praying in tongues is a cleanser that helps purge the spiritual “grunge” that has built up in our hearts. Praying the Spirit is like walking on the beach at sunrise or climbing to the top of a mountain and taking in great draughts of the clear alpine air. As we pray, the sickening, toxic fumes from the devil begin to dissipate. Speaking in tongues is a way to allow the Holy Spirit to saturate and fill every pore of our being, body, soul, and spirit. It helps establish a holy atmosphere around us and those for whom we pray. We have a responsibility to monitor and, if necessary, change the atmosphere in our homes. Fear, anxiety, depression, and other noxious gases from the devil invade our homes through television, radio, the internet, books, magazines, and newspapers. Bad news and frightful situations assault our senses on a daily basis. Prayer can change the atmosphere—prayer that exalts the name of Jesus.
