they shall inherit the earth.”
The idea of the meek inheriting the earth is found throughout the Book of Psalms. When someone is poor in spirit and mourns over his own sins and the sins of others, pride and arrogance are eliminated. A person who knows he is no better than the rest will not be easily lifted up above his brothers and sisters. But this meekness does not imply lack of power, or spineless passivity. It is power, but it is power under the control of love and without the poison of self-interest and self-seeking.
To have power, and to use that power only for the good and well-being of others, is meekness. Jesus perfectly demonstrates how power that operates through meekness cannot be quenched, whereas temporal power and people who play politics always come to a bad end.
