The truth of scripture is that at unexpected times Christ comes to all of us, either in blessing or condemnation. That's why we are exhorted to be waiting and watchful. In Jesus' day many people were not prepared in heart, mind and soul for the Messiah's coming to them. They would not repent of their ungodly actions and attitudes. 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.
