God - be glorified - sets a seal on the heart of the disbeliever, and lays a covering on his eyesight and an impairment on his hearing lest he may understand and believe
Therefore, anyone speaks to the unbeliever, whom God does not like to guide, and tells him every evidence, argument and proof, the unbeliever will not respond (unless God wants to guide anyone
So some may have a misconception that disbelievers or atheists do not believe because of defective argument and that they do not find it logical because the belief is wrong and the religion of God is wrong!
No, it is not like that
God Himself does not want them to believe, but He sends the apostle to be an argument against them lest they should not say in the Next Life: we were not warned and no apostle came to us.
So the angels will tell them: apostles and warners came to you, but you only mocked and ridiculed, so now suffer the chastisement. In fact God did not guide you, because you were wrong-doers
God - be glorified - said in the Quran 2: 7-8

. Surely, those who deny [you, Mohammed, and the Quran]; it is the same to them – whether you warn them or you warn them not – they will not believe. a

God has set a seal [of "Rayn" which is the rust] upon their hearts and [deafness] on their hearing, and on their sights is a veil [lest they should convert] b, and there awaits them a grievous chastisement

a Because they are wrong-doers: they wrong people; and God does not guide the wrong-doer, but misguides him
The indication of this is His saying – be glorified – in the Quran 14: 27 which means: (God misguides the wrong-doer, and God does what He pleases
b because they are wrong-doers, and God does not guide the wrong-doer
