This is the result of God's Glory flooding the earth (Habakkuk 2:14)
And they will not need to teach their neighbors, nor will they need to teach their relatives, saying, ‘You should know the Lord.’ For everyone, from the least to the greatest, will know me already,” says the Lord. “And I will forgive their wickedness, and I will never again remember their sins.” http://bible.us/Jer31.34.NLT
