So there's basically a few chords to go with the song

They are Am7, D, F/G, And C. Through the entire song.

And then there's that part that goes " I can't believe what god has done... something something. "

That part starts with Fmaj7, to an E7, and then back to the main chord progression.

F/G (303211@1)             C (x32010@1)But isn't she lovely made from love

Isn't she pretty
Truly the angel's best
Boy, I'm so happy
We have been heaven blessed
I can't believe what God has done
Through us he's given life to one
But isn't she lovely made from love

Isn't she lovely
Life and love are the same
Life is Aisha
The meaning of her name
Londie, it could have not been done
Without you who conceived the one
That's so very lovely made from love
