The "baptism of the Holy Spirit" refers to a spiritual experience in which a person receives the Holy Spirit, often associated with empowerment for service and a deeper relationship with God. This event is commonly linked to the teachings of Jesus and the early Christian church, particularly in the New Testament. Many believers view this baptism as a distinct experience from water baptism, emphasizing its role in spiritual transformation. It is often accompanied by signs such as speaking in tongues or other spiritual gifts, reflecting a profound change in the individual's faith journey and connection to the Christian community.
