There is no change from Matthew 5:5.
On earth, if one is meek, one might not attempt to improve one’s situation. The meek might not seek to improve their status. Thus, they represent powerlessness. However, in the next life, those who are meek because of their circumstances on earth will be able to change places with the mighty. They may not inherit power on earth, but they will in heaven.
Of course, as with all of the beatitudes, each of these conditions assumes that the person who is represented by the trait is faithful in living the gospel.
