I understand what you mean Bettie, but I'm going to (sort of) agree with the reviewer.  
 
This is a complete thought:
When God created a mother He made her resilient, because He knew the pain she would suffer from her child's arrival until her death. (I actually added a comma here.)
He made her loving, because only she can kiss away the pain when her child is hurt.
 
Etc.
 
Your way creates a super long run-on sentence. They are all thoughts that go together - agreed. But when punctuated with periods and made into one paragraph, they are easier to read and follow the thought. If you really wanted/needed it all as one paragraph, the proper way to punctuate would be with semi-colons because within each thought you have a comma. A semi-colon denotes a "heavy duty" pause or separation of thought. It's particularly useful when listing complicated items that need a comma within them.
 
"Words in a series" would be:
Joan bought lemons, apples, pasta, eggs, and chicken at the grocery store.
 
One use of semi colons:
The speakers at the dinner included, John Brown, Mayor of Smallville; George WHite, owner of White Autos; and Martin Black, Citizen of the Year Honoree.
 
Here's yours repunctuated with semi colons:
When God created a mother He made her resilient, because He knew the pain she would suffer from her child's arrival until her death; He made her loving, because only she can kiss away the pain when her child is hurt; and He made her patient, because a mother must be patient and understanding to meet and confront the troubles her child must face at times.  
I am so glad that God made my Mom all of these things for me.
OR
I am so glad that God made YOU all of these things for me.  
 
(And I changed this a little because of switching back and forth between first person and third person. I still may not have it 100% right. I think you were trying to get "mom" or "mother" in that last sentence. Just my opinion.)
 
 
 
 

I agree with Susan that semi-colons are a good way around this. But I read recently that a semi-colon should never be followed by 'but' (or 'and' and various other conjunctions). That was news to me but just pointing it out in case the reviewer knows about it too!

I'm glad to hear that, Sue, because I've been doing it all the time!  

Thanks, Sue - and thank you for the blog link. It looks as if a lot of people are using quote marks simply for emphasis and it's possible that may gradually become an accepted use of them. (Language is constantly evolving!)
 
I gave my daughter the book you mention but I only dipped into it. Another good one, more on language in general is John Humphrys' 'Lost for Words'.
 
When I was tutoring privately, I could always tell when my pupils had been doing apostrophes in class because they would suddenly start to put them by each and every letter 's'. The rule is so simple really and yet I suspect that many of the teachers are unclear about their use!
