A person who takes in a homeless child wins the lottery

basically it means what you give you get.

I believe it does. I had my first husband leave me for a hottie. she later left him for a hunk and he came crawling back. I didn’t give him the time of day. You make your bed-you have to lie in it. Look before you leap! Things are not always what they seem. (More home truths wraped up in sayings)

You every tell a lie and the hard you try to make it right the lie gets bigger and bigger. well that another example.

One thing to always remember is “do onto one as you would want done onto yourself”.
