Focus on the family teenage dating
Many parents set rules for their Christian teens about dating.
If a teen is dating another Christian, there is a greater likelihood that they will remain abstinent and supportive of one another.
The Solution: You can set the rule, but also leave it open for your approval. Don't grill him or her about their faith, but get to know him or her to evaluate whether or not you think this teen shares your child's values.
Pros: Dating that occurs in public places prevents temptation from getting the better of teenagers. Cons: Just saying that the dating has to occur in public places does not necessarily ensure that the people around your Christian teen will hold him or her accountable.
While all of these rules are appropriate, it will be easier for your teen to follow your rules if they understand where the rules come from.
Don't just cite Scripture -- explain how it applies.
