What don't you understand about Islam/the Qur'an?

I'm sorry but it's the things that I do understand that I find very disturbing.And my heart goes out to anybody caught up in that religion.Jesus said Whom the Son sets free is free indeed.Now that's what I call good news.And according to what's written in John 3:16 in the Holy Bible, all are welcome to come to God on His terms.Hope this helps.
