Your Father Loves You by James Packer, Harold Shaw Publishers, 1986, page for August 31
The meek are those who know themselves to be poor in spirit, who have learned, honestly and from their hearts, to regret all the dehumanizing and subhuman things in which they have been involved as wanderers in this lost world, and who now in humility want only the will of God. "Moses was very meek, more than all men that were on the face of the earth" (Num. 12:3>). His meekness was shown in his acceptance of what God ordained, including endless battles with those recalcitrant and disappointing people whom he was trying to lead from Egypt to Canaan, including, even, the enormous disappointment of himself not getting into the Promised Land.
Moses was a man with a fierce temper&md;it was this which had betrayed him during the time in the wilderness&md;but when God said, in effect, "Now look, Moses, in order to teach the whole world how much loss sin can bring, I'm not going to let you enter the land; the people will go in, but you won't," he did not curse God in furious protest; quietly, if sadly, he accepted God's decision. That's meekness. Meekness, for a child of God, means accepting uncomplainingly what comes, knowing that it comes from the hand of God who orders all things. What he sends, we accept in faith even if it hurts, knowing that it's for our and others' good.
Those who are meek&md;that is, prepared to forego their rights in this world, if that's what God requires of them&md;will inherit the earth: they will be made infinitely rich in the future. I think Jesus was referring to the riches of heaven more than to earthly blessings when he spoke, echoing Psalm 37:11>, of inheriting the earth. Mercies promised in earthly forms in the Old Testament regularly turn out to have celestial content in the New.
