Why Allah's Message Failed To Convince All Humans?
This test whose result God already knows is the will of God. He intended to do this, this way. This is not His test of knowledge, but our test of conscious efforts. We have to go through it to earn our end whatever it is. He wanted to reward those who make it and punish those who fail, with their own free choice, knowingly, with no excuse. All this would happen if it happens. so it is happening. Had he willed, He would have had us put in this test without our consent, but He told us, that He, graciously, did take our consent. and we willingly rather, perhaps, enthusiastically consented to it (see 33:72).
