Not sure what to make of this

I am trying to understand why this song is speaking to me... the Lyric, "Can circumstances possibly change who I forever am in You" stands out most for me... 

I might not completely understand the rain and the dark clouds but I choose to sing, "Holy, holy, holy is the Lord God Almighty". 

"Bring The Rain" - MERCYME

I can count a million times
People asking me how I
Can praise You with all that I've gone through
The question just amazes me
Can circumstances possibly
Change who I forever am in You
Maybe since my life was changed
Long before these rainy days
It's never really ever crossed my mind
To turn my back on you, oh Lord
My only shelter from the storm
But instead I draw closer through these times
So I pray

Bring me joy, bring me peace
Bring the chance to be free
Bring me anything that brings You glory
And I know there'll be days
When this life brings me pain
But if that's what it takes to praise You
Jesus, bring the rain

I am Yours regardless of
The dark clouds that may loom above
Because You are much greater than my pain
You who made a way for me
By suffering Your destiny
So tell me what's a little rain
So I pray

Holy, holy, holy
Is the Lord God Almighty
