Fact of the matter is, even if God showed Himself to humanity, those not willing to believe will not believe and those willing to believe will believe…
The case in point, the Jews were shown 7 incredible miracles of of God through Musa :as:…The plague, the parting of the seas, the first borns dead, the turning of the river into blood, the miracles through Musa :as: e.t.c…
What happened after a few days? In a couple of months in fact? The created a golden calf and started worshipping it…Even after being open witnesses to these miracles…
What happened when the Jews were shown miracles through Isa :as:? The same ones who witnesed these miracles turned against him and tried to kill him…
And there are countless and thousands of examples in which people have been shown miracles and proof of God, but they turned back…Is it the fault of God that even after witnessing such great events they turned back?
The Quran talks about such people thus:
Surah Baqarah
1. Alif-Lâm-Mîm. [These letters are one of the miracles of the Qur’ân and none but Allâh (Alone) knows their meanings.]
2. This is the Book (the Qur’ân), whereof there is no doubt, a guidance to those who are Al-Muttaqûn [the pious believers of Islamic Monotheism who fear Allâh much (abstain from all kinds of sins and evil deeds which He has forbidden) and love Allâh much (perform all kinds of good deeds which He has ordained)].
*3. Who believe in the Ghaib [1] and perform As-Salât (Iqâmat-as-Salât),[2] and spend out of what We have provided for them , spend on themselves, their parents, their children, their wives, etc., and also give charity to the poor and also in Allâh’s Cause - Jihâd].
4. And who believe in (the Qur’ân and the Sunnah )[4] which has been sent down (revealed) to you (O Muhammad صلى الله عليه وسلم) and in that which was sent down before you [the Taurât (Torah) and the Injeel (Gospel), etc.] and they believe with certainty in the Hereafter. (Resurrection, recompense of their good and bad deeds, Paradise and Hell).
5. They are on (true) guidance from their Lord, and they are the successful.
6. Verily, those who disbelieve, it is the same to them whether you (O Muhammad صلى الله عليه وسلم) warn them or do not warn them, they will not believe.
7. Allâh has set a seal on their hearts and on their hearing, (i.e. they are closed from accepting Allâh’s Guidance), and on their eyes there is a covering. Theirs will be a great torment.
8. And of mankind, there are some (hypocrites) who say: “We believe in Allâh and the Last Day” while in fact they believe not.
9. They (think to) deceive Allâh and those who believe, while they only deceive themselves, and perceive (it) not!
10. In their hearts is a disease (of doubt and hypocrisy) and Allâh has increased their disease. A painful torment is theirs because they used to tell lies.
11. And when it is said to them: “Make not mischief on the earth,” they say: “We are only peace-makers.”
12. Verily! They are the ones who make mischief, but they perceive not.
So, when someone says, ‘Oh, homosexuality is OK’ then he is following disbelief despite being shown clear signs…
In this regard, who is to be blamed? Allah :swt: for sending down the laws or you disregarding them?
You can’t argue with Allah :swt:…He has sent down His commands and let you free to follow them or disregard them…In the end, who will be to blame for the consequences of your actions?
Read the verses I quoted in detail…See what Allah :swt: is saying…He is telling you that this book contains all that He wishes you do…If you don’t, then there is none to blame but yourself…
