Questions about No Matter What from Boyzone

Could I ask a question?

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

But there are different versions and I just got confused.

Could somebody help me?

Thanks in advance.

Its lyrics are as follows:

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 I'll love forever Is it " I know I'll love forever" or " I know our love's forever?"

I know, no matter what                (Because there are two versions.)

                                                1) 

                                                2) 

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 sheltered from the storm  Is it "shelter from the storm" or " 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 Is it " no matter what the end is" or "no matter what the ending?"

My life began with you
