I heard this yesterday on Al Mohler’s The Briefing, and found it today in the young lady’s own words over on The Gospel Coalition. This is a profile not only in courage to confront evil, but a boldness to speak of the beauty of the gospel to her abuser. This is a must watch, as we should all aspire to be able to react to the harms others may do to us like Rachel Denhollander did. No further comment on my part can add to her powerful testimony.
EDIT Update: you may need to go to about 25:30 in to get to the essential part of the video. Initially the link took you directly there.
