God did not say that His house would be a house of worship, great preaching, wonderful community programs, outreach or discipleship...He said that it would be a HOUSE of PRAYER! Those other things are absolutely vital to the health of the church, but not if first things are not first. Without being a HOUSE of PRAYER, all of the "things" we do for Him will not be established...but if we are a HOUSE of PRAYER, everything we declare & everything work of our hands will be established. See how Jesus felt about it in Luke 19:46...
