I think the author does a great job at continually stressing human depravity and saying that repenting of one "major" sin does not acquit one of all other sins. Also, she does a great job at expressing the idea that getting married isn't God's solution to homosexual temptations but that the ultimate goal in life is to grow closer to God and glorify him and anything that doesn't encourage that (homosexuality being one of a multitude) is the wrong direction.
