Luke 7:47

47. Wherefore Our Lord now furnishes his reply to the silent query of Simon, whether this professed prophet discerns spirits, by showing him that he did most truly discern both her spirit and his. And so he also settled Simon’s other query as to the rightness of allowing this female sinner to approach and touch him. Penitence and sanctification have made her pure, and gratitude, moreover, by her feeling of the greatness of her sin, her ruin, and her salvation, have wrought this paroxysm of love, and these acts of humility.

Her sins are forgiven Jesus does not here address the woman and now pardon her sins; he addresses Simon, and informs him that the reason of her much love is that she is one much forgiven; and forgiven before he has announced the fact to her, and even before the rich display of her love. Her gratitude is in effect a consequence, a manifestation and proof that her sins are forgiven.
