One of the things that makes me most sad about the world today is the prevailingly negative attitude towards marriage, especially the idea that marriage doesn't "work." As a newlywed of only four months I know that I don't have much credence with the general public regarding marriage, but I think I do understand what marriage really is, and I can say with a good amount of certainty that whether or not marriage works isn't really up to marriage, bless her little abused heart. It's up to the people who are married.
Marriage is a commitment. It's saying, this is the person I want to do the dishes with, the person I want to come home to, the person I want to encourage and dream with, the person I will sacrifice for, but most of all, the person I will commit to, come what may.
Everyone has heard that love is a feeling, but marriage is a choice. And when you get married you're saying I'll always chose you.
So, John, my dear, I love you, but more importantly, I'll always chose you.
And that's how I can know that we'll be just fine.
