‘‘The message of the cross is foolishness to those who are perishing, but to us who are being saved, it is the power of God’’ (1 Corinthians 1:18).
Is Paul not apostolic? Did he not say ‘‘all which do not love Jesus Christ are accursed’’ (1cor 16:22).
Any religion out there, despite their hatred toward Jesus christ, despite their commitment to idolatry, despite their commitment to worshipping God through demonic excerpts uses, etc, etc, can all be saved If they just are overall good people?
But do they really hate Jesus? or do they hate some false figure that they are told is ‘Jesus’?
No matter what, they will ONLY be saved through Jesus. That’s a truth.
But look at the people who died before Jesus was born. Did they know Him? Nope. . .but if they were saved, and many we know were, wasn’t it through Jesus? If they did not know Him as the God-Man who walked the earth from approximately 4BC to AD 29, they most CERTAINLY knew Him in some other way.
The Father, Son, and Spirit are one. Therefore the many great Jewish OT saints knew Jesus in the Father. To this day, there are Jews and Muslims who ‘know’ Jesus through the Father and thus MAY be saved, even if they speak ‘wrongly’ of Jesus Christ, because the "christ’ they are told of is not the TRUE Christ. Think of it: To Jews he was a crazy blasphemer. Was Jesus a crazy blasphemer? NO! Therefore, to ‘reject’ Jesus as a crazy blasphemer means you are not really rejecting Jesus. You’re rejecting a false image which is called’ Jesus’ but is not. To Muslims, He is a prophet, but not God. Is Jesus God? Of course! Muslims have been taught a false Jesus so they ‘reject’ His godhood but they do not necessarily reject the TRUE Jesus. For if the Jews and Muslims know the Father, they know the true Jesus, and if they are saved it is through that belief in the True even while they might speak and reject the ‘false’ jesus.
For others who don’t believe in God at all, it might be that they reject a false god --the person they have been told is ‘god’ is some bloodthirsty intolerant ‘myth’. Is God a bloodthirsty intolerant myth? NO! Therefore, what these people ‘reject’ as god is NOT REALLY GOD at all. And so, they might still be saved for while they reject a false ‘god’ even thinking that the falsehood represents ‘truth’, they might still know in their hearts (as people did before God manifested Himself to the Jewish people and then through them in Christ), the ‘true God’ and thus be saved.
It certainly behooves us to evangelize and speak the TRUTH, but WE cannot judge the heart of another or claim WITH CERTAINTY that a given person who supposedly ‘rejects god’ might not reject the True God, or might not repent at death, AND BE SAVED.
