If someone is genuinely worshipping the Abrahamic God, even if in an incorrect way which they wholeheartedly believe to be correct, do they not get a chance to correct themselves when the Mashiach comes and clarifies everything?
This is something that I wrestle with as I look at the world and see various people of faith. While Islam and Christianity are existing outside of the truth of Torah, they have faithful individuals who practice the worship of the Abrahamic God in a way they truly believe to be right.
All three are waiting for the Mashiach.
All three believe in sin and repentance for sin.
All three believe in a Messianic Age.
All three are worshiping the Abrahamic God (though Christians warped their definition of this).
This is especially true with Islam in that the Muslims live a lifestyle which mirrors certain aspects of Judaism. They have similar meat prep practices, Shia Muslims don't eat shellfish, there are modesty rules for men and women, worship services separate the sexes, they pray multiple times a day, etc. etc. etc.
There is obviously a long list of reasons why these groups do not agree on everything and why we believe some are more wrong than others. I'm not speaking to the nature of those issues.
If these groups are clear that they believe they are worshipping the Abrahamic God, if these groups believe they are doing so in a way they 100% believe to be correct (even if falsely) and they are living a life in hopes for the coming Messianic age.
If this is all the case, does this mean there would be a period of time where the Mashiach will come and clarify the truth in the message and then give people a chance to change?
