There are different types of Pentecostal churches. Most believe that you must be saved by believing in Jesus as their Savior; to be forgiven for their sins and to be pleasing to God. Pentecostals also believe, like most other evangelicals, that the Bible is true and must be obeyed in decisions of faith. In this majority group, speaking in tongues is the sign of the Baptism of the Holy Spirit and is not required for salvation. To this group, the Baptism of the Holy Spirit is a supernatural gift for ministry that one receives after they have become a Christian.
