"Christianity is also the hardest religion in the world because, if you believe Christ died for your sins and rose from the dead, you have no choice but to give your life entirely over to Him. NO MORE SEXUAL PROMISCUITY, no lying, no cheating, no stealing, no killing inconvenient old people or unborn babies – no doing what all the other kids do."

It is a sin.
However, it CAN be forgiven.
The fact that forgiveness is a possibility is the point of the article and a distinctive point of christianity.
