2 Mark what follows: “Blessed,” says He, “are the meek, for they shall inherit the earth.” You wish to possess the earth now; take heed lest you be possessed by it. If you be meek, you will possess it; if ungentle, you will be possessed by it. And when you hear of the proposed reward, do not, in order that you may possess the earth, unfold the lap of covetousness, whereby you would at present possess the earth, to the exclusion even of your neighbour by whatever means; let no such imagination deceive you. Then will you truly possess the earth, when you cleave to Him who made heaven and earth. For this is to be meek, not to resist your God, that in that you do well He may be well-pleasing to you, not you to yourself; and in that you suffer ill justly, He may not be unpleasing to you, but you to yourself. For no small matter is it that you shall be well-pleasing to Him, when you are displeased with yourself; whereas if you are well-pleased with your own self, you will be displeasing to Him.
