So high I almost touch the sky

Do you think in the song "Wind beneath my wings" when Bette Midler sings "Thank you, thank you, thank God for you, the wind beneath my wings", she is actually thanking some higher power, or is she just using the conventionalized expression "Thank God for X"? The answer to this question really has the potential to impact my enjoyment of the song. (I won't say which interpretation I'd prefer. )
