Does the bible paint a picture of a good God, claimed to be a God of Love? What about the version of God as 'revealed' by Mohammad?
The Bible explicitly claims (by revelation at that) that God is just, merciful, and compassionate. God is perfect, God loves us (John 3;16 For God so loved the world...). And God is defined as perfect. And there are numerous verses of the Bible that tell us what is meant by merciful, just, compassionate and merciful. Which means theists cannot go on to claim that mercy or compassion means something different with God than these words mean when applied to mankind. See Isaiah 1 for examples of what is meant by merciful and good.
As for the Quran, we have Qadr, Allah's predestination. God leads who he will and leads astray who he will lead astray. I found 28 examples in the Quran that claim we are what we are due to Allah.
Nor is that to be found only in the Quran.

Ezekiel 11
18 And they shall come thither, and they shall take away all the
detestable things thereof and all the abominations thereof from thence.
19 And I will give them one heart, and I will put a new spirit within
you; and I will take the stony heart out of their flesh, and will give
them an heart of flesh:
20 That they may walk in my statutes, and keep mine ordinances, and
do them: and they shall be my people, and I will be their God.
And with the "Great Commission" of Mark 16 and Matthew 28, God could do this for Christians.
So much for the free will arguments that Christians offer up to explain moral evil and great horrendous suffering that follows moral evil.
Romans 11. Why did the Jews not accept jesus as the messiah? God hardened their hearts not to do so. Why not harden their hearts to believe? Why not all mankind?
