The following is from Jonathan Edwards sermon,
“Safety, Fullness, and Sweet Refreshment in Christ”

The godly man carries his indwelling sin, as his
daily and greatest burden, because he loathes it,
and longs to get rid of it; he would fain be at a
great distance from it, and have nothing more
to do with it; he is ready to cry out as Paul did,
“O wretched man that I am! who shall deliver
me from the body of this death?”

The unregenerate man has nothing of this
spiritual nature, for sin is yet his delight, he
dearly loves it. His love to sin in general is
not mortified, he loves it as well as ever, he
hides it still as a sweet morsel under his tongue.
