The Father made a PROMISE to His people. As 120 gathered together on the day of Pentecost, they would come to realize the PURPOSE of the promise. They would receive the power of God to become true witnesses. When the Holy Spirit fell on each of them, like tongues of fire, the PLAN of God was unleashed. Author D.L. Formhals helps the reader understand the Biblical plan to baptize all believers with the Holy Spirit and Fire.
