Vision depends altogether upon the condition of the organ. The eye sees only what it brings the means of seeing. The scaled eye of a worldling, or a debauchee, or a self-righteous man, cannot see that sin of the heart, that “spiritual wickedness,” at which men like Paul and Isaiah stood aghast. These were men whose character compared with that of the worldling was saintly; men whose shoes’ latchets the worldling is not worthy to stoop down and unloose. And yet they saw a depravity within their own hearts which he does not see in his; a depravity which he cannot see, and which he steadily denies to exist, until he is enlightened by the Holy Ghost.
