"Baptism in the Holy Spirit" refers to a spiritual experience in which a believer receives the Holy Spirit in a profound way, often associated with empowerment for service and a deeper relationship with God. This experience is commonly linked to the events of Pentecost, when the Apostles were filled with the Holy Spirit and began to speak in different languages. Many Christian denominations view this baptism as a distinct event from water baptism, emphasizing its role in equipping believers for ministry and spiritual gifts. It is often accompanied by signs such as speaking in tongues or prophetic utterances, reflecting a transformative encounter with the Holy Spirit.
