|2 Corinthians 6:17-18|
2 Therefore "'come out from among them, and be separate,' says the Lord, 'and touch no unclean thing; and I will receive you. '
And I heard another voice from heaven, saying, "Come out of her, my people, so that you do not share in her sins, and so you will not receive her plagues. Rev 18:4
Some of God's people are still in Christendom Babylon; God is pleading with his elect to leave the false churches. You will never see salvation if you stay in Babylon, who promises you heaven even though you still sin — who tells you that you must physically die before experiencing heaven — who tells you that you will go to heaven and escape Hell (saved) by believing that Jesus is the Son of God and/or being water baptized.
