Whether by 2027, or not, I have no idea.
However, Revelation 13 does indicate that a one world religion is coming - worship of the antichrist or death.
I know that for years people have thought that the one world religion would be some watered down blend of catholicism, protestantism, hinduism, buddhism, and islam.
The others might be willing water down what they believe, but I don't think that islam would.
However, the worship of the antichrist, who blasphemes everything that is worshipped or is called god, doesn't sound like islam, or any blend of the others.
He will oppose all those beliefs, including blaspheming the God of Israel, as well as islam's allah.
Perhaps some zealous muslims may give him a mortal head wound.
But that's it, after his apparent resurrection, it will be worship him or die.
Perhaps many young people around the world, growing up in those different religions, may immediately be drawn to his rebellious blasphemy, and be some of his first adherents.
Look at what's reported to be going on in Iran, many young people want nothing to do with islam - thankfully a number are believing on Jesus.
But I think the majority are just turning away, and many are turning back to their ancient zoroastrianism.
