Every knee will bow. I think you meant receiving Christ.So devout Muslims will be given eternal life on the new Earth without knowing or even rejecting Christ ???
When we receive a saint of the Lord are we not receiving Christ whom sends Him? The least of these my brethren? So then people of other faiths have indeed received the Lord and served Him....by serving His brethren. That's more than many believers have done.
I don't know about atheists. Fear of the Lord is required for righteousness. There is a holiness commandment after all.That's an UR core verse from Scripture, hope you realize.
God's mercy does not stop at death, not in Scripture, but it comes down what you are preaching here.
Matt 25:31 “When the Son of Man comes in his glory, and all the angels with him, then he will sit on his glorious throne.
Matt 25:32 Before him will be gathered all the nations, and he will separate people one from another as a shepherd separates the sheep from the goats.
Matt 25:33 And he will place the sheep on his right, but the goats on the left.
Matt 25:34 Then the King will say to those on his right, ‘Come, you who are blessed by my Father, inherit the kingdom prepared for you from the foundation of the world.
Matt 25:35 For I was hungry and you gave me food, I was thirsty and you gave me drink, I was a stranger and you welcomed me,
Matt 25:36 I was naked and you clothed me, I was sick and you visited me, I was in prison and you came to me.’
Good news for Atheists ??
