If you look closely at Genesis you may notice that humanity doesn’t have a morality problem but a holiness one.
Islam is a false and violent religion; but, it is one that seeks to be moral in certain ways that are still valid despite the rest. That is as you would expect given that it’s true authors were out to deceive and destroy men who still knew certain things about morality (though not all).
But Islam, like all false religions, can do nothing about unholiness.
Yet even a Muslim, unholy though they are, can still have aspects of morality that a grossly immoral person cannot, having cast aside moral judgment for ideological ones.
In Revelation, at least speaking for myself, I think we see there being conflict on the Earth right up to the end, meaning that the whole world may be affected by AC’s kingdom but not necessarily part of it. I look at our times as if Satan’s kingdom is presently being split into camps for this conflict with some Caliphate of unholy yet trying to be good people warring against those who are convinced that they are nice and tolerant but are simply immoral as well as unholy. Thus there is a broad way leading to destruction for those who want to be good and one for those wanting to be nice and both get to congratulate themselves that they are better than those people (while both will viciously seek to harm the Saints).
Interesting and accurate.
