I believe Muzzies will be shocked, too.
However, I also believe God meant what He said when HE SAID that those who earnestly SEEK HIM, shall find Him.
Therefore, it would not surprise me that God turns out to be amazingly merciful to folks of true heart who, doing the best they knew, sought ALMIGHTY GOD in the way they were taught.
John 14:6 -- 6 Jesus said to him, I am the way, the truth, and the life. No one comes to the Father except through Me."
Yes. If one seeks one shall find. And what they shall find is the only way to the Father: Jesus.
The problem with many muslims is that they are not seeking truth, they are following a lie. Seeking that lie will lead to hell.
