I remember most of the lyrics to this song from when I was little... It was probably the mid to late 90's, but the song might be older. Here are the lyrics as I remember them:

There's a time to be a child, and a time to be naive
..............
But the fairytale has ended, as all children's stories do
Now I'm looking at the world from a different point of view

(Chorus)
I'm tired of pretending
I've left the child behind
To Jesus I'm surrendering,
My heart and soul and mind
From this day on I'm going to be,
A woman of God for the world to see
Light of Truth come shine through me...
I'm tired of pretending...

(Bridge)
The world may say, I have so far to go,
But as I grow, Lord, let it show, let it show...
