The oxford online dictionary defines the word
abound as follows:
abound: Exist in large numbers or amounts.
abound in/with Have in large numbers or amounts.
but, today I came across the following statement:
Generally in life you have to learn to abase and abound.
I am familiar with the word abase, it's meaning is apparent. But what does it mean to "learn to abound"? I certainly don't suppose it means to learn to exist in large numbers.
