These passages are taken from Spurgeon's most excellent sermon on the third beatitude, found here. Highly, highly recommended!

"The meek in spirit are like a photographer’s sensitive plates—as the Word of God passes before them, they desire to have its image imprinted upon their hearts. Their hearts are the fleshy tablets on which the mind of God is recorded. God is the Writer and they become living Epistles, written not with ink, but with the finger of the living God! Thus are they meek towards God."
"When a man is converted, the first operation of the Grace of God within his soul is to give him true poverty of spirit, so the first Beatitude is, “Blessed are the poor in spirit.” The Lord first makes us know our emptiness and so humbles us. Then next He makes us mourn over the deficiencies that are so manifest in us. Then comes the second Beatitude, “Blessed are they that mourn.” First, then, is a true knowledge of ourselves and then a sacred grief arising out of that knowledge. Now, no man ever becomes truly meek, in the Christian sense of that word, until he first knows himself and then begins to mourn and lament that he is so far short of what he ought to be. Self-righteousness is never meek."
"It is true that it has a relationship to God, but a man’s meekness is especially towards his fellow men. He is not simply meek within himself—his meekness is manifest in his dealings with others. You would not speak of a hermit who never saw a fellow creature as being meek. The only way in which you could prove whether he was meek would be to put him with those who would try his temper."
"The meek-spirited man may be naturally very hot and fiery, but he has had Grace given to him to keep his temper in subjection. He does not say, “That is my constitution and I cannot help it,” as so many do. God will never excuse us because of our constitution—His Grace is given to us to cure our evil constitutions and to kill our corruptions!"
"If you take your brother by the throat because he owes you a hundred pence, can you think that God will forgive you the thousand talents which you owe Him? So the meek-spirited man forgives those who wrong him—he reckons that injuries are permitted to be done to him as trials of his Grace, to see whether he can forgive them—and he does so, and does so right heartily."
"The meek-spirited man is not ambitious. He is satisfied with what God provides for him. He does not say that his soul loathes the daily manna. And the water from the Rock never loses its sweetness to his taste. His motto, is, “God’s Providence is my inheritance.”
"If we are meek, we shall the more readily see the excellences of other people."
"With a gentle temper and a quiet spirit, and Grace to keep you so, you will be inheriting the earth under any circumstances. If trouble should come, you will bow to it as the willow bows to the wind and so escapes the injury that falls upon sturdier trees. If there should come little vexations, you will not allow yourself to be vexed by them, but will say, “With a little patience, they will all pass away.”
"But this must be the work of Grace. We must be born-again, or else our proud spirits will never be meek."
"Put those five qualities together and you have the truly meek man—humble, gentle, patient, forgiving and contented—the very opposite of the man who is proud, harsh, angry, revengeful and ambitious. It is only the Grace of God, as it works in us by the Holy Spirit, that can make us thus meek."
"There are some people who are very gentle and meek as long as nobody tries them. We are, all of us, remarkably good-tempered while we have our own way. But the true meekness which is a work of Grace will stand the fire of persecution and will endure the test of enmity, cruelty and wrong—even as the meekness of Christ did upon the Cross of Calvary.
"The meek-spirited man is glad to know that other people are happy—and their happiness is his happiness! He will have a great number of heavens, for everybody else’s Heaven will be a Heaven to him! It will be a Heaven to him to know that so many other people are in Heaven, and for each one whom he sees there, he will praise the Lord. Meekness gives us the enjoyment of what is other people’s, yet they have none the less because of our enjoyment of it!"
