Muhammad states that the words of God cannot be altered and are incorruptible and affirms the writings of Moses and the gospels specifically. It therefore affirms the bible and the bible says there are not other valid teachings that differ from it therefore the Quran is false as is all of Islam.
Well, that'd be all nice and dandy, except the Bible itself has been "altered" through the ages, and Christians can't even agree on what it's supposed to say, much less on what it's supposed to mean. Oh, and that's a slight misrepresentation of what Muhammad, supposedly, said and how he intended it to be applied. But let's not worry about such small things

Sin is an offense against God, a breaking of his law....I've explained this all before....repeatedly actually.
"Offense against God". What does that even mean? How can a non-corporeal, non-human entity be "offended"? More than that, how can I be sure that God has a law and that it's what you claim it to be? Or that he even exists? You can't keep putting the cart before the horse.
It’s unsubstantiated only by the body of unbelievers and that opinion is of zero concern or consequence to me…..I don’t take counsel on God from atheists.
It's unsubstantiated, period. That's perfectly fine and nothing (and nobody) is stopping you from believing something that's unsubstantiated, but don't pretend that your belief is based on anything short of "feels". There's no substantive difference between your belief and the belief of a someone who follows, say, Shamanism.
He desires for you to be aligned with him in righteousness, but he allows you to choose to defy his will and have no God in your life and your eternity.
If he desires this, why does he not reveal himself to me? I mean, he had no problem showing his ass to Moses (Exodus 33:23) and I'll just settle for a phonecall! So either he doesn't desire for me to be aligned with him in righteousness or his plan doesn't give him free nights-and-weekends calling.
No one makes you sin or reject God.
Not true: if noone
makes me sin, then Jesus isn't needed because it would be possible to live a sinless life and achieve my own salvation and that would render your Messiah moot. Indeed, the central tenet of Christianity is that we're
born with Original Sin and that we have a sinful nature that we
cannot, on our own, escape. In other words, under the Christian ethos, it is impossible for me to not sin and that's the reason why Jesus is necessary: to save us since we can't help but sin by paying the price of sin for us.
Easy validation is that God wants you to choose him and today you’re still an atheist and will be again tomorrow and the day after that…..choices have been made.
One wonders, how I can make a choice when the Bible clearly says that it's all predetermined and God knows the outcome. There is no way to reconcile free will with the Bible.
We break laws so we get punished. Laws are meaningless without consequences.
But it is, at least, possible for us to live
without breaking human laws. The same is simply
not possible with God's laws, which makes those laws unjust. And unjust laws shouldn't be followed.
