Working like Jacob

Jacob worked for years to earn the wife he loved. I was advised to get fit, do Jogging( which I am not doing, I am doing walking instead) to earn a wife. I think doing it just to be fit is wise, but I was told to do certain things to get a wife just like Jacob got racheal. this morning I was reading a chapter in a book and that very same thing was mentioned. It felt like God saying the advice you have been given and have taken is good. Keep doing it.
