ZOEgirl - Dead Serious lyrics

Who's that girl with the Bible in her hands
The smile on her face, she doesn't get it, I don’t understand
The way she walks with her head in the clouds
She doesn't care who laughs, walks right through the crowd

That's right, that's me, I don't care what you think
People talk all day, I don't care what they say

You think I'm delirious, a typical reaction
Aren't you curious about my satisfaction
Maybe you're envious, a little curious
You can laugh, but I'm dead serious

Watch her as she goes, there's something different and she knows it
Ask her why, and she'll flash that silly smile
She says she's got a purpose and she's done with all the games
Jesus saved her soul and she'll never be the same

That's right that's me, I don't care what you think
You can talk all day, I don't care what you say

Eternity won't wait for me
I've made my choice, it's where I want to be
All I want to be seen is the light of God shining in me
I may be young, but I am free
You can't change what I believe

That's right, that's me, I don't care what you think
You can talk all day, I'm okay anyway

Serious, I'm serious
You can laugh but I'm dead serious

I love this song. More so the meaning behind it rather than the beat of the song. It is, however a cool, upbeat song. Have any of you heard it before?
