What distinguishes Pentecostal belief regarding the Holy Spirit?

Pentecostal belief is characterized by the idea of a second baptism, often referred to as the "baptism in the Holy Spirit." This belief emphasizes that after a person initially accepts Jesus Christ as their Savior, they can receive an additional outpouring of the Holy Spirit that empowers them for service and witness. This experience is often accompanied by speaking in tongues and other spiritual gifts.

Pentecostals view this second baptism as a distinct and transformative experience that deepens one's relationship with God and equips the believer for ministry. This concept is rooted in passages from the New Testament, particularly in the Book of Acts, where the disciples experience a powerful filling of the Holy Spirit following Jesus' ascension.

This focus on the second baptism distinguishes Pentecostalism from other Christian denominations that may not emphasize a subsequent experience of empowerment by the Holy Spirit in the same way.
