Suppose I really like drinking (alcohol of course). Mormonism teaches that God is against alcohol. If I believe God exists then I will have to believe I am wrong in drinking alcohol.
It's an assumption that if a person believe a God exists then this God must be 100% exists, and therefor the teachings of that God must be 100% true.
If a person try to believe a God exists although afterthat he fail to remain that beliefs because he see no convincing evidence to support that beliefs, does this God really exists to him?
The moral of a God that it's wrong for drinking alcohol, only comes to be subjective morally true in non-believer's subjective reality after the existence of that God have been substantiated to him.
Now since I don't want to stop drinking alcohol I would prefer it if God doesn't exist. So I reject all evidence (or supposed evidence) of his existence simply because I don't want to change my lifestyle.
Whether one wants to change his lifestyle or not, doesn't means/prove that the validity of all the supposed evidence to be valid/true.
It can be he don't want to change his lifestyle, and all the supposed evidence is valid/true.
Or all the supposed evidence is not valid/true regardless of whether he wants to change his lifestyle or not.
In this case it is clear that I simply want to drink no matter what. And even if God was proved to exist to my satisfaction I would still likely continue drinking becase that is what I want to do.
It's another assumption that if "God was proved to exist to one's satisfaction he would still likely continue drinking becase that is what he want to do".
Possibility:
1. The person could be genuinely see no convincing reason/evidence of God's existence, so he don't believe in God, therefor he also don't follow the God's teachings.
2. The person actually believe/know that God exists but dislike the God's teachings, so he lie that the evidence is unconvincing and God doesn't exists in order for him not need to follow the God's teaching.
How do we know whether he genuinely see no convincing evidence of God's existence or not?
In order for we to know if he's genuine or not, we examine his reason why he think so, but the standards of logic/reasoning we use in that examination may vary from people to people, so it depends on examiner which have different standards.
How do we know if he do believe/know God exists but is lying in order not need to follow the God's teachings?
By examine his reason to conclude whether he is lying or not? Again the result of this examination is depends on different standards of logic/reasoning of different examiner.
Or we could use lie detector to know whether he is lying or not, though i'm not sure the result is 100% accurate.
The people who lie is lying and may continue to lie.
The people who speak honestly is speaking honestly and may continue to speak honestly.
Whether they lie or speak honestly doesn't prove the validity of God's existence.
1 ---> some believer of some religion/God may advise non-believer to follow their God or religion/God's teachings ---> non-believer may ask evidence for God's existence or religion/God's teaching's validity ---> believer may give evidence or explain the method how to obtain the evidence ---> non-believer may say that the evidence is unconvincing or the method is not working ---> believer may disagree ---> they may disagree with each other ---> non-believer may remain their disbeliefs while the believer may remain their beliefs ---> they continue to live their life whether it's with beliefs or lack beliefs in any God ---> (go back to 1)
