I love the definition of meek:
Blessed are the meek; for they shall inherit the earth.
This one seems hard to believe. Maybe this is how we believe the world should be, but not how we see it.
Emmett Fox describes meekness as meaning a mental attitude which is the secret of prosperity or success in prayer. It is a combination of open-mindedness, faith in God and a realization that the will of God for us is always something joyous, interesting and vital, and much better than anything we could think of for ourselves. This state of mind also includes a willingness to accept this plan of God's will coming in the way He wants, not as we choose.
Moses is an example of this kind of meekness. He had an open mind, and was ready to be taught new ways of thinking and doing things. Emmett Fox says of Moses, "He was not, in the beginning, free from serious faults of character, but he was too big for intellectual or spiritual pride, and therefore he gradually rose above his defects, as the new truth worked in his soul."
