Pray that the saints would experience the filling of the Spirit outwardly by taking the way of repenting and dealing with sin, believing in the accomplished fact, obeying God, praying with one accord, and meeting to pursue the outward filling (Acts 2:38; 5:32b; 1:14a; 2:1, 4a; Hymns, #276).
Acts 2:38—Repent…each one of you…for the forgiveness of your sins, and you will receive the gift of the Holy Spirit.
Acts 5:32b—The Holy Spirit, whom God has given to those who obey Him.
Acts 1:14a—These all continued steadfastly with one accord in prayer…
Acts 2:1, 4a—As the day of Pentecost was being fulfilled, they were all together in the same place…And they were all filled with the Holy Spirit.
