Whistle on the wind

I've never been reminded of the joy I have to give
Like the day I realised my life was really truely lived
For when you said you read it as it whistled on the wind
My heart burst forth its banks and I learnt to understand the need
You called me to return and asked of me to please believe
I wandered in and out your clouds and heavens light was received
And I said if God be willing perhaps my work complete and done
But you said dear child, you know that it has only just begun
