Doubting Thomas lyrics

What will be left when I've drawn my last breath
Besides the folks I've met and the folks who've known me
Will I discover a soul-saving love
Or just the dirt above and below me

I'm a doubting Thomas
I took a promise
But I do not feel safe
Oh me of little faith
[ Lyrics from: http://www.lyricsmode.com/lyrics/n/nickel_creek/doubting_thomas.html ]
Sometimes I pray for a slap in the face
Then I beg to be spared cause I'm a coward
If there's a master of death
I bet he's holding his breath
As I show the blind and tell the deaf about his power

I'm a doubting Thomas
I can't keep my promises
Cause I don't know what's safe
Oh me of little faith

Can I be used to help others find truth
When I'm scared I'll find proof that it's a lie
Can I be led down a trail dropping bread crumbs
That prove I'm not ready to die

Please give me time to decipher the signs
Please forgive me for time that I've wasted

I'm a doubting Thomas
I'll take your promise
You've always kept me safe
Oh me of little faith
