This document discusses the baptism of the Holy Spirit and praying in tongues. It describes how Jesus told his disciples to wait for the Holy Spirit after his ascension. On the day of Pentecost, the 120 believers were filled with the Holy Spirit and began speaking in other tongues. Praying in tongues allows one to pray directly to God, strengthens and builds up one's spiritual life, helps worship God, and can open the doorway to other spiritual gifts. The conclusion states that praying in tongues is a powerful means of communicating with God through the Holy Spirit and can increase one's love for Christ, God's word, God's work, and the lost.
