Martin Lloyd-Jones on Sin

We tend to think of sin as we see it in rags and in the gutters of life. We look at a drunkard, poor fellow, and say, there is sin. But that is not the essence of sin. To have a real picture and a true understanding of sin, you must look at some great saint, some unusually devout and devoted man, look at him there on his knees in the very presence of God...Or, to put it in a different form, if you really want to understand something about the nature of Satan and his activities, the thing to do is not to go to the dregs or the gutters of life. If you really want to know something about Satan, go away to that wilderness were our Lord spent forty days and forty nights. That’s the true picture of Satan, where you see him tempting the very Son of God.
