Which doctrine teaches that the Holy Spirit endows believers for service and witness?

The doctrine that teaches the Holy Spirit endows believers for service and witness is indeed centered on the concept of the Baptism in the Holy Spirit. According to Assemblies of God beliefs, this experience empowers individuals to fulfill their divine purpose, equipping them with spiritual gifts and boldness for ministry, evangelism, and service to others.

The emphasis on the Baptism in the Holy Spirit is rooted in biblical passages, particularly in Acts 1:8, where Jesus promises that the Holy Spirit will empower His followers to be witnesses. This event is understood as a separate and distinct experience from salvation, providing believers with a deeper relationship with the Holy Spirit and enabling them to operate in the gifts of the Spirit. Therefore, this doctrine is foundational for understanding how the Holy Spirit actively works within believers to accomplish God's mission in the world.
