Debt vs Bargain! The Deathmatch of the Century!

So my wife is planning a trip to her country of origin, and she is taking the kids with her. I'm not going because the money that we've put away isn't quite enough for all of us to go, so I get to be the one left behind; besides, I don't have enough vacation for the amount of time that my wife and the kids are going to be there.

Nevertheless my wife insists that I should buy a ticket and stay for as long as I can. I've been opposed to this idea because I've been against accruing debt since the beginning of our marriage. Oh, yeah, there is that thing about the Lord suggesting that we should avoid debt; that is a bit of a influence too.

My wife, being ever the optimist, is still trying to convince me to go. She has a couple of arguments that certainly get me thinking about it. First, she says that airline fares are really low right now -it was part of the reason we decided that her and the kids should go now- and it's true, and do we know if prices are going to be this low for very long or at least return to these prices by the time we have the money saved up? Second, when we all go down we want to tour the whole country and see people that we knew on our mission. Let's face it, these people aren't getting any younger and neither are we. The longer we wait the more things are going to change, and it's already been ten years.

So here I am trying to decide between time, price and debt. Do it now and we'll be in debt a while. Do it later and risk paying more, and missing more than we already have. I still lean in the direction that we should avoid the debt and save. Have faith as it were. It's not easy and I certainly don't like the idea of even more time passing but that is what faith is all about I guess.
