A Consequence of Their Own Decision
[6:111] Even if we sent down the angels to them; even if the dead spoke to them; even if we summoned every miracle before them; they cannot believe unless GOD wills it. Indeed, most of them are ignorant.
Anyone who chooses God will see the miracles, but for those who refuse to believe in God will be blind to all the miracles right in front of them.
