Here I Am Send Me Delirious?

[Verse 1]
Show me a vision like Isaiah saw
Where the angel touched his lips
And he sinned no more
Let me hear Your voice saying
"Whom shall I send?"
I'll say send me Lord
I'll follow You to the end

[Verse 2]
Show me a vision like Ezekiel saw
An army of light
From a valley of bones
Breathe life into these lungs of mine
So I can scream and shout
Of Your love divine

[Pre-Chorus]
Search light, burns bright
Floods my eyes
Invade me serenade me
I'm giving back my life

[Chorus]
Here I am send me
Here I am send me
There's nothing in my hands
But here I am send me
