Wildfire ?

Because there is a flame in my soul 
It sparked with no flint 
It started to grow 
I thought it would scare me
But it didn't 

Instead it is the life 
That breathes into me 
It doesn't burn 
Simply enlightens me

No. more than that 
It is the passion 
flowing through my veins 
Instead of blood
I am fueled with flames  

I need to find a way 
To make it bigger and brighter 
With no matches 
Or lighter 

The sparks my word makes 
It catches quick 
And then creates 

And when there's nothing 
Left but ashes 
I form them into a key 
The only thing it'll ever fit in 
Is the keyhole it burned in me 

To unlock more and more 
Till everything is burned 
That's impossible to ignore 

For if theirs nothing left
To fuel my thoughts 

I will become the gasoline 
and light up the dark hearts 
By setting fire to their dreams
