The will is a beast of burden. If God mounts it, it wishes and goes as God wills; if Satan mounts it, it wishes and goes as Satan wills; Nor can it choose its rider...The riders contend for its possession.
Men are great or small in stature as it pleases God. But their nature is great or small as it pleases themselves. Men are not born, some with great souls and some with little souls. One by taking thought cannot add to his stature, but he can enlarge his soul. By an act of the will he can make himself a moral giant, or dwarf himself to a pygmy.
