Did you know that the word in our bibles that was translated to "meek" literally meant "teachable"?
And thus, those who are teachable shall inherit the earth.
Further, there actually was no word in the original text that translated to "shall". It was put in as a filler for our "understanding". Thus, it's not something that is to come, but rather something we already possess if we are teachable.
It makes more sense in this scripture though:
You (shall) know the truth and the truth (shall) set(s) you free.
