Pentecostals believe that the baptism with the Holy Spirit is available to all Christians. Repentance from sin and being born again are fundamental requirements to receive it. There must also be in the believer a deep conviction of needing more of God in their life, and a measure of consecration by which the believer yields themself to the will of God. Citing instances in the Book of Acts where believers were Spirit baptized before they were baptized with water, most Pentecostals believe a Christian need not have been baptized in water to receive Spirit baptism. However, Pentecostals do believe that the biblical pattern is "repentance, regeneration, water baptism, and then the baptism with the Holy Ghost". There are Pentecostal believers who have claimed to receive their baptism with the Holy Spirit while being water baptized.
