I think scripture tells us that we are all born with a nature to sin. Weather it is idolatry, lying, fornication (see the 10 commandments)...and sometimes it can manifest itself in same sex attraction. I also think certain situations could exacerbate the issue--like if there was sexual abuse or bad parental relationships. The devil will use these as poison arrows against fallen humanity, which he hates.

I too went the same route as the parents in the article. My heart is also broken. I am old now and all I can do is pray for my child.....I used to blame myself and the fact that we were a Military family and Dad was gone alot. Both my children have Disabilities.....I've come to the conclusion that some sins seem to be more "attrackable" then others and we as a fallen people fall into sin if we don't keep a watch on our hearts. Some prople are prone to following the crowd and get into difficulties and then find it very hard to overcome. I just pray that God will have mercy on our fallen children and help them back to SEE JESUS.....I pray for young parents these days. As I read and listen to the news it's going to get harder and harder to raise a child to be a firm standing follower of Jesus.
God have Mercy on us........A TIRED OLD MOTHER.......
