Appreciate your comment.

Alot in there but I will focus on two bits.

You likened Allah to a mother calling after her children. The Quran however is super clear that Allah has no children. The only relationship one can have with him is a slave to master relationship.

Secondly, in Islam, you submit to Allah by submitting to Muhammad according to Surah 4:65 and 4:80. And in submitting to Muhammad, it gets very complicated because he does, forbids and approves of all manner of things in the Hadith. So it is not as straightforward as saying "just submit to God".

And based on this, a Christian who submits to God is not a Muslim because Christians don't believe in Muhammad.
