There is not enough pew space to accommodate this idea. But if mandatory which church would be made the established place to go? RCC? JW? Mormon? Presbyterian? Baptist? Episcopalian? The local Mega? Franklin Graham's public meetings? PCUSA (Sodomite version)? Methodist? Lutheran? Pentecostal? Charismatic? Assemblies of God? Wesleyan? Prosperity Gospel? etc. If everybody was forced to join such a myriad of confusion then they would have to increase the ministry training to fill all these pulpits. And when they did not get enough volunteers for the pulpits they would have to press gang them into service.
They would also have to close down the Mosques, Synagogues and Hindu temples.
Its a good job God made HIS Church only a Remnant.
Romans 11:4 But what saith the answer of God unto him? I have reserved to myself seven thousand men, who have not bowed the knee to the image of Baal.
5 Even so then at this present time also there is a remnant according to the election of grace.
6 And if by grace, then is it no more of works:
"no more of works"? ~ Oh Does that cut out the Arminians?
