When do we draw the line?

Yesterday I went to the movie Something Borrowed with my bestie, Nicolette. I haven't seen Nicolette in forever. Nicolette and me have a tradition of watching as many movies as we can when we see each other. We used to sit up in my room and watch movies on my dad's laptop (when I didn't have one) all the time. Idk why, but we've continued that tradition on. And so, when we finally were both in the same town we hit up three, yes THREE, movies (and of course watched another one at home).
We went to Kung Fu Panda 2 and Green Lantern at the drivein in Luverne. Which, if you live in Sioux Falls or surrounding area and are looking for a fun date and/or hang out place. Go there! It's only $5 per person for two new movies. Yes, it is in Luverne and the drive is not short, but it's worth it (just don't go on a weekend, supes busy). And yesterday we went to Something Borrowed. I had heard so many different reviews on it and from the one time I had seen the preview (which was prolly like 5 months ago) I wanted to see it. Well, I actually really liked it. But! I had such a hard time enjoying it. Movies are getting harder and harder to discern. The whole time I was mad because there was cheating going on. But at the same time, all I could do was hope the guy, Rex, would call off the wedding and end up with the girl he was cheating with. They were obviously a better fit. But was that the right thing to hope?
Marriage is so much more than just something to be thought of so carelessly. Marriage is made by God. But nowadays it's just another thing we like to try out for a while. If it works, then hey! Guess we won that one. If not, well I guess we can always try again. But that's not God's desire for us in marriage. God hates divorce (Malachi 2:16).
Although, I honestly think that in the movie the two characters that "fit" the best could have worked out (aka no divorce) and that the other two would most definitely have ended up divorced, can I really know for sure that a couple without God would actually make it? I was thinking about that as the movie ended (and hopefully I didn't give away the ending to any of you who wanted to see it). It breaks my heart to think that there are so many couples out there getting married because of THEIR love. But our love is nothing without God. God is love (1 John 4:7). We are not.
At the end of all my questioning of this movie I realized that I am so glad that I have God to hold my marriage to David together. I know it won't be easy, in fact there will be days it will be impossible on my own. But, I know that Christ will hold us together. And that excites me so much! I am so blessed!

Aren't blogs with pictures so much more fun?!? I think so. So here's a picture of me and my fiance, David.

So, I guess the question here is "When do we draw the line?" Why are we, as Christians, just sitting back and enjoying things opposite to God's Word? And how can we live so that others might see our set-apart life?
