As it is written, every knee shall bow and every tongue shall confess that Jesus Christ is LORD (Romans 14:11). Notice that this does not say that "all Christians" or "everyone who makes the cut into Heaven" shall confess that Christ is LORD.
EVERY knee shall bow, and EVERY tongue shall confess, even if it is accompanying a desperate cry for an end to the eternal torments of the pit of hell.
Even avowed atheists, whether they like it or not, have the Law of God written on their hearts - yet further proof that they are deluded fools, lying even unto their selves.
Romans 2:14-16
For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves:
Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another; )
In the day when God shall judge the secrets of men by Jesus Christ according to my gospel.
Pay attention, atheists. The Law is written on your heart. You WILL confess that Jesus Christ is LORD. You don't have to
burn in hell. Do yourselves a favor,
stop being stiffnecked, and pull your heads out of your asses. We want you to turn your lives around and become Christians, so that you may join us in Heaven.
Amen.
