Paul doesn’t seem to worry that his declaration of his own struggle with sin will encourage us all to sin more. He knows that he is weak, and he has told us this time and time again and even dared to boast in his weakness. Paul does not seem to be tied up in knots about his ongoing sin problem, but he moves seamlessly and immediately to doxology. It is dazzling. Paul does not spend hours, days, months and years agonizing over his sin, as we often do. This kind of morbid misery doesn’t help us sin less; it simply leads to more and more cycles of sin.
