Praying like in Pentecostal / Charismatic Churches violates the teaching of Jesus above.
When I walked into a church I was visiting the entire church was praying in tongues. Jesus revealed to me that this was His will for the church. This experience taught me that you have to know God's will. Jesus then led me to join them. Tongues is one of the gifts and the scriptures tell us they won't cease until we are transformed and face to face with Jesus, which is when the gifts will no longer be needed.
