How does a nice girl like Bristol Palin....

....from a nice family......whose parents believe in abstinence for teens.......get pregnant at 17?
I'll tell you. For the whole "abstinence" thing to work, there has to be at least 4, if not 6 people commited to it. Here goes:
1 The girl must believe that physical intimacy before marriage is wrong.
2. The boy must believe that physical intimacy before marriage is wrong.
3 The girl's mother must believe that physical intimacy before marriage is wrong, and be willing to take the time and effort to make sure that her daughter is never in a situation where violating this principle is even remotely possible.
4 The girls father:ditto
5.The boy's mother: ditto
6.The boy's father:ditto

The Bible says that "a child left to himself bringeth his mother to shame" Kids get into trouble when there are no adults present. Its just that simple. When both parents work, it easy for kids to fall between the cracks of parental vision. Even when mommy doesn't work, she sometimes lets her guard down.

"But I trust my daughter!" You shouldn't. God doesn't. He told you to keep an eye on her.
"I trust my son" Your son needs your guidance.
As a pastor's wife, I've heard it all. "My daughter know what she is supposed to do!" "My son would never do that!" Look, this is bigger than you or your daughter. Just "knowing" what is right or wrong in not enough! Christian young people know that they are in sin, and they are grieved by it, but thats not enough. Be prepared to do you job!
