The song "No Matter What"

I know I’ve posted the questions before, but could I ask for help again?

Because I got no replies last time and I really need to know the answers.

Sorry for bothering so much.

Could someone help me out?

Please excuse me for my poor English listening ability.

Thank you so much.

I googled the lyrics of the song No Matter What from Boyzone.

But there are different versions and I just got bewildered.

No matter what they tell us

No matter what they do

No matter what they teach us

What we believe is true 

No matter what they call us

However they attack

No matter where they take us

We'll find our own way back

I can't deny what I believe

I can't be what I'm not

I know our love forever 

Question 1: Is it “I know I'll love forever” or “I know our love forever?”

I know, no matter what 

If only tears were laughter

If only night was day

If only prayers were answered

Then we would hear God say

No matter what they tell you

No matter what they do

No matter what they teach you

What you believe is true

And I will keep you safe and strong

And shelter from the storm  

Question 2: Is it "And shelter from the storm" or " And sheltered from the storm?"

No matter where it's barren

A dream is being born

No matter who they follow

No matter where they lead

No matter how they judge us

I'll be everyone you need

No matter if the sun don't shine

Or if the skies are blue

No matter what the end is 

Question 3: Is it " No matter what the end is" or "No matter what the ending?"

My life began with you
