A question frequently asked in Christian relationships is, How far can we go physically? This question is really asking, How close can we get to the line without crossing over into sin? By contrast, the chastity principle asks, How pure and holy can I be? Sex is God's wedding gift, and He does not want it to be opened early! Avoid behavior you would one day regret if your relationship were to be broken off. The safest approach is to treat the person you are dating as if he or she might be someone else's spouse (cf. 1Thes. 4:3-7) (Rick Holland).
