Speaking in Tongues is mostly for prayer, but when we come together, it should be interpreted supernaturally. Shaul says in 1 Corinthians 14:39 CJB, "Do not forbid speaking in tongues." Those who receive the Holy Spirit should seek gifts of the Holy Spirit (see 1 Corinthians 14:1).
1 Thessalonians 5:21 CJB says, "Test everything - hold onto what is good." Again, what God gives us is good. The Ruach HaKodesh means the Holy Spirit. Luke 11:11-13 CJB says, "Is there any father here who, if his son asked him for a fish, would instead of a fish give him a snake? or if he asked for an egg would give him a scorpion? So if you, even though you are bad, know how to give your children gifts that are good, how much more will the Father keep giving the Ruach HaKodesh from heaven to those who keep asking him!"
