It's a secular song and not by a Christian group (I think), but when I hear "The Reason" by Hoobstank, I think of God and praise Him:

I'm Not A Perfect Person.
There Are Many Things I Wish I Didnt Do
But I Continue Learning.
I Never Meant To Do Those Things To You.
And So I Have To Say Before I Go,
That I Just Want You To Know

I've Found A Reason For Me,
To Change Who I Used To Be
A Reason To Start Over New,
And The Reason Is You

I'm Sorry That I Hurt you,
Its Something I Must Live With Everyday
And All The Pain I Put You Through,
I Wish That I Could Take It All Away
And Be The One Who Catches All Your Tears,
Thats Why I Need You To Hear

I'm Not A Perfect Person,
I Never Meant To Do Those Things To You
And So I Have To Say Before I Go
That I Just Want You To Know

I've Found A Reason For Me,
To Change Who I Used To Be
A Reason To Start Over New,
And The Reason Is You
I've Found A Reason To Show
A Side Of Me You Didnt Know
A Reason For All That I Do,
And The Reason Is You

I really like this song. I loved singing it when my 17 year old son was in hearing range. (He doesn't believe in God.) It sometimes got a conversation going about none of us being perfect, and there only being one that is perfect and He is our reason for us to learn and change. So far, I am the queen . My son has moved to his father's where he doesn't hear about the Word.
