Are young marriages the solution to sexual immorality?

Both solutions are faulty. Young marriages aren't the solution unless the person has found his or her soulmate. A person should not get married for the sole purpose of having sex. They should get married because they are READY, and because they are in love. Waiting until 25-30 also isn't a good idea if a person is ready for marriage. The key to getting rid of sexual immorality is through education (not this modern liberal stuff we have in the schools, btw), a good example from parents and others around them, as well as keeping youth away from things that promote it such as certain music, tv shows, movies, magazines, etc. It won't work for ALL people, but it would probably help a lot.

Is there such thing as a soulmate? The idea is very much a modern and western one.

The Bible says that the main reason for Christians to marry is to prevent fornication- in other words, marrying to have sex.

Sex is filthy and dirty!! Save it for someone that you love!!
