Black History Month: February 13th!
Long, long time ago, there used to be Tarrying Rooms in many Pentecostal churches, where believers would "tarry" for the Holy Spirit. The idea of "tarrying" for the Holy Spirit came out of the Pentecostal Revival which started in 1906 around the turn of the 20th century.
Now there were many in the Pentecostal movement in those days that believed, preached and taught that you had to tarry to be filled with the Holy Spirit. Also, the idea of “tarrying” for the Holy Spirit is rooted in Luke 24:49 and Acts 1:4, and finds an historical counterpart in the Pentecostal Revival which started in 1906 at the Azusa Street Mission in Los Angeles.
There, according to His promise to restore all things, God began to pour out His Spirit upon all flesh, manifesting "the Gift" and "gifts" of the Holy Ghost - exactly like it was in the early church. From here the Pentecostal revival spread around the world like wild-fire. Signs, wonders and divers manifestations of God's Spirit were multiplied beyond number.
