You will not do any work in your lifetime that is more important than the keeping of your wedding vows . In accepting to undertake that work, you accept the responsibility of marriage.
Up until this point in relationship, much of your shared life has been about courtship. When people say, "oh, marriage will not change our lives, we're so married anyway," you're not. What's different about marriage is not the paper but the vows.
You make promises to one another. Keeping those promises means keeping your word. It means considering your partner's well-being. It means working to keep the relationship whole and healthy so that both of you, and any children who may wander into the equation, may be whole and healthy.
Your long-term goals for this marriage are describing of the work needed to achieve them. There is no sense in making promises if you are not intending to keep them . Forever. You are promising to be responsible to and for these promises. Forever. You are promising to be responsible to and for these promises.
Our integrity is the most central thing to who we are . We want to be, need to be, known for both being exactly who we are and for keeping our word. Someone suggested not long ago that not everyone is cut out for monogamy. That's fine. But why make promises about monogamy if you can not keep them? "I'll lose my beloved if I do not make those promises." Why, yes, you will. You'll lose him or her even more horribly if you cheat. Which is to say, cheat on your partner and cheat on your promises.
Let your wedding ceremony reflect your dedication to these wedding vows. Your community will hear you and understand their importance. Because you have honored them by asking them to be witnesses to those promises, they will do everything they can to help you succeed. And then live boldly into those promises and into your sound, working marriage. Something this wonderful is worth working for.
