"But you, beloved, building yourselves up on your most holy faith, praying in the Holy Spirit, keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life." Jude 20-21.
"Behold, I send the Promise of My Father upon you; but tarry in the city of Jerusalem until you are endued with power from on high." Luke 24:49
"When the Day of Pentecost had fully come, they were all with one accord in one place. And suddenly there came a sound from heaven, as of a rushing mighty wind, and it filled the whole house where they were sitting. Then there appeared to them divided tongues, as of fire, and one sat upon each of them. And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit gave them utterance." Acts 2:1-4
Every person who has received Jesus Christ as Savior and Lord (been born again) is a candidate for Baptism in the Holy Ghost with the evidence of speaking in tongues as the Spirit gives utterance. On the Day of Pentecost, the 120 persons assembled in the Upper Room were filled with the Holy Ghost and began to speak with other tongues as the Spirit gave them utterance. Not only was the ability given to speak in tongues, but also to pray in tongues.
"For they have healed the hurt of the daughter of My people slightly, Saying, 'Peace, peace!' When there is no peace....For the hurt of the daughter of my people I am hurt. I am mourning; Astonishment has taken hold of me. Is there no balm in Gilead, Is there no physician there? Why then is there no recovery For the health of the daughter of my people?" Jeremiah 8:11, 21-22
Isaiah says Jesus is Wonderful, Counselor, Mighty God, Everlasting Father and the Prince of Peace. (Isaiah 9:6) Through praying in tongues, the Holy Ghost acts as our Counselor and allows us to "talk out" out problems as we pour out our hearts to God about our troubles. "casting all your care upon Him, for He cares for you." 1 Peter 5:7 This is especially good for believers who are victims of abuse or who have emotional problems. Truly in Jesus, there is a cure. God has a remedy for everything. He can build us up, take us through difficulties and be our Counselor - all through praying in tongues.
Apostle Paul said, he who speaks in a tongue speaks to God and edifies himself. (1 Corinthians 14:2, 4) Staying in the love of God requires self-edification. This is especially important when a believer is experiencing adversity or difficulty.
Praying in tongues is a means of sowing to the Spirit as opposed to sowing to the flesh. For he who sows to his flesh will of the flesh reap corruption, but he who sows to the Spirit will of the Spirit reap everlasting life." Galatians 6:8 We know that whatever a man sows, he will reap. (Galatians 6:7) By praying in the Spirit, we can sow to the Spirit and expect to reap life everlasting. "But the fruit of the Spirit is love, joy, peace, longsuffering, kindness, goodness, faithfulness, gentleness, self-control. Against such there is no law." Galatians 5:22-23
"The Spirit of the Lord is upon Me, Because He has anointed Me To preach the gospel to the poor; He has sent Me to heal the brokenhearted, To proclaim liberty to the captives And recovery of sight to the blind, To set at liberty those who are oppressed" Luke 4:18
Praying in tongues also helps us overcome our weaknesses and infirmities. (Romans 8:26) Sometime we experience deep hurts that are hard to express and difficult to overcome. The Holy Ghost makes intercession for us, allowing us to talk directly to God as He searches our hearts. (1 Corinthians 2:10:11) God specializes in healing the brokenhearted. One of the ways to receive such healing is by praying in the Spirit.
"But as it is written: 'Eye has not seen, nor ear heard, Nor have entered into the heart of man The things which God has prepared for those who love Him'." 1 Corinthians 2:9
