Some versions of the bible use the word fornication, while others use sexual immorality. Also, there's that list in Leviticus 18 of commandments on who you shouldn't sleep with, being relatives, animals, the same sex, and it doesn't say anything about premarital sex. Paul is clear about having sex before marriage, but I'm,not sure if Jesus ever really said anything about sex before marriage. I am wondering if sexual immorality includes fornication. Or could it mean just things like whoredom and promiscuity. It feels to me like there is morality in a committed unmarried relationship with the possibility of marriage as opposed to one night stands. Does God want me to save myself for marriage? I want to obey Him but I'm not sure if this is actually his commandment.
