It then discusses passages from Acts where Jesus commands the disciples to wait in Jerusalem to receive power when the Holy Spirit comes. The document emphasizes that salvation is through being baptized by the Holy Spirit into Christ, water baptism is an outward symbol performed by disciples, and Jesus baptizes believers in the Holy Spirit. It examines examples of these three baptisms from the book of Acts and relates them to the Old Testament tabernacle.
