When we pray in tongues, a river of life flows out of our spirit (where the Holy Spirit dwells) through our mouth: “out of his heart will flow rivers of living water” (John 7:38). This divine river carries life, healing, supernatural power and gifts. Hilary shares the results of medical studies showing that extended praying in tongues activates areas of our brain which release hormones, resulting in increased immunity from sickness, and health for our minds and bodies.
