Welcome to this wonderful forum. It's good to have you here.
I have volume four of the Big Book and I think that the paragraph that you are after is found on page 417. It's in the personal story called 'Acceptance Was The Answer'. If it is the paragraph that starts “And acceptance is the answer to all of my problems today.” then that's where it is. (Apologies if I have got it wrong!).
“For us, material well-being always followed spiritual progress; it never preceded.” is from Big Book (volume four). It's on page 127 and it's from the chapter 'The Family Afterward'. The paragraph starts 'The head of the house ...'
I do hope that helps.
Take care,
Carol

thanks for responding - someone else did have the answer to both: the acceptance thing is on p. 417 and the material succes thing is on p. 127. this website is great! ed
