Having the Talk About Marriage

Till death do us part... It's a daunting proposition. That's probably why half of marriages (faith-based or not) throw in the towel at some point along the way, and why more and more people are choosing to either put off or pass up on marriage altogether. Is marriage an outdated concept? Can it really work? Can two people actually stay together? What "talk" would Jesus and the Bible have about marriage in this day and age?
