What the preacher man must have been saying is...
If you painted a beautiful picture and are proud of the job you did,

Who should get the credit?

You could say God is the puppet master so God did it.
Or everything is Gods work even ours.
You could say something like God provided me with everything to enable me to paint this picture. The glory is his. And so on.

Or you could say you did it and have your own self esteem instead and thank the big bang.

Behold a picture has been painted by anonymous.
