Gee, you're right.
At age 15 it's more like 3 seconds of physical climax, against an eternity of suffering.
And all these self-indulgent folks DON'T think anybody (at any age past-potty training) has ANY self-control of ANY body functions ???
We have been told the results of refusing the Law .... I'm going to pretend that those who "want" a nicely liberal, peaceful, ignorant, get-everybody-to-heaven God exists .... but there are dozens of Gospels PROMISING hell to those who follow their physical want-be-do and don't request forgiveness, practice self-control, and act correctly while living.
Even more showing the hypocrisy and ultimate failure of trying living for only a pleasureable life on earth.
We don't know what happened on this boy's deathbed between him and God ..... but we do know that his "friends" aided and encouraged not only a felony (sex with a minorr), but a misdemeanor (prostitution) and the "non-criminal" penalties of disobeying the hospital staff, his parents, and the hospital rules.
What he did with God when he died I don't know. Let uts hope this behavior was not an indication of that ... but soemthing tells me that he did not truly ask forgiveness for his sins.
Ill ask again... WHERE in the Torah/Tanach (your "old" testament) is fornication a sin?
HINT: ITS NOT THERE. So, suppose this was a Jewish boy. Are you now damning him because he broke one of the "new" laws?
