These people were religious but not Godly. Religious people go through the forms of worship to keep alive the nostalgia of their past. For them, worship was only an intellectual exercise that left out the heart. Godly people worship with their heart and head. Godly people live to glorify God and to enjoy Him forever.
Religious people live for the success of the organization.
Godly people are looking for the wave of God's blessing. Religious people try to make their own waves of blessing. Church history tells of many times when Christ came to a community or a nation in revival blessing. These were times when the holiness of God burned like a refiners fire. Before the service would begin people would come streaming to the altar to get right with God.
