Matthew 5:18,19

"For amen I say to you, Until upward vision and land may come along beside, one jot or one tittle will in no way come along beside, from the law, until all things are becoming. Whoever therefore may loose one of the least of these directions, and thus teach humanity, will be called least in the realm of upward vision, but whoever may do and teach them, the same will be called great in the realm of upward vision."  One day our land and the realm of upward vision will be coming along beside one another. And then "all things are becoming."  Therefore "these directions" that Jesus is setting forth, these principles of living, are vital to the new realm.  To "loose" or let go of these teachings of upward vision, is devastating.  To forsake the directions concerning poverty, justice or peace (just laid out) is to be "least in the realm of upward vision."  To be "great" in the sense intended here, is simply to be found doing and teaching the principles of the realm.
