... they will probably do as most godly kids do...wait.
Just some food for thought, that's all. But in my experience as a trusted counselor to a lot of Godly people (Christian teens and young adults) over the years, a huge percentage of them didn't wait. But most of them will either avoid the subject with very tactful answers that don't really answer the question, or they will just lie and say they
are waiting unless you can win their trust enough for them to talk honestly with you. (They even do this with each other!) They have had it drilled into their heads so strongly that sex outside of marriage is such an unforgivable sin that they honestly feel that they are now condemned to hell for doing it, and that there is not enough power in the sacrifice of Jesus to save them. Of course, the results of this drilling were not the intention of the well meaning drillers, but this is the result nonetheless. So they just can't bear to admit what they have done.
This is not to say that no one waits. Just that a awfully large percentage (in my experience) do not wait.
Of course, I suppose also that a lot has to do with the definition of "Godly". If the definition of a Godly person is one who waits until marriage, then I suppose you can say that none of those people were Godly, therefore those who
are Godly wait. But that's just circular reasoning and not valid. If you compare people's actions to the
whole word of God (instead of just focusing on one particular subject), you will probably find it very hard to even find one "Godly" person based on their actions alone.
A lot of damage has been done to many of God's fine children by putting so much of a guilt trip and so much pressure on them over this subject!
Ok, go ahead and flame on me now. But whatever your view on this subject, I'm just speaking the honest truth from very real observation.
