My Salvation (Isaiah 12)

I've not written much lately, but here's a song I wrote a while back based on Isaiah 12.
It's been running through my head recently, so I thought I'd share:

God of mercy, God I praise,
turning your anger away
Humbly bearing consequence
to pay the price for my all sins 

A fountain flowing purest light,
a spring of life that won’t run dry
Oh, my portion, God on high,
in you my soul is satisfied 

My strength, my song, You have become my salvation
My strength, my song, You have become my salvation 

God almighty, hear my praise,
You have done such glorious things
All the earth will know Your name,
the thirsty soul will proclaim 

A fountain flowing purest light,
a spring of life that won’t run dry
Oh, my portion, God on high,
in you my soul is satisfied 

My strength, my song, You have become my salvation
My strength, my song, You have become my salvation
