There have been more than I shall list but here are a few:
You never know what you can do unless you try.
You can do anything you REALLY set your mind to.
Do unto others as you would have them do unto you.
No one is any better than anyone else.
God helps them who help themselves.
Don't wander too far;you might get lost.
People in glass houses shouldn't throw stones.
The grass on the other side of the fence has just as many weeds.
There are more but the best advice I EVER got in my life was that God so loved the world that He gave His only begotten Son, that whosoever believeth in Him should not perish but have everlasting life!
