The following is from John Flavel's, Keeping The Heart.
"Perhaps the smallness of the sin is urged as a reason why you may commit it: "It is but a little sin--a small matter--a trifle!"
But, if you commit this little sin--you will offend a great God! Is there any little hell to torment little sinners in? No! The least sinners in hell are full of misery! There is great wrath treasured up for those whom the world regard as little sinners.
The less the sin--the less the inducement you should have to commit it. Will you provoke God for a trifle? Will you destroy your peace, wound your conscience, and grieve the Spirit--all for nothing? What madness is this!"
