Keeping our vows

I'm preaching at a wedding on Saturday and have been giving some thought to the awesomeness of the promises we make when we marry. Then I came across this on Benjamin Warfield:
Benjamin B. Warfield was a world-renowned theologian who taught at Princeton Seminary for almost 34 years until his death on February 16, 1921. Many people are aware of his famous books, like The Inspiration and Authority of the Bible. But what most people don’t know is that in 1876, at the age of twenty-five, he married Annie Kinkead and took a honeymoon to Germany. During a fierce storm Annie was struck by lightning and permanently paralyzed. After caring for her for thirty-nine years Warfield laid her to rest in 1915. Because of her extraordinary needs, Warfield seldom left his home for more than two hours at a time during all those years of marriage.
We all promise to love our spouses for better or worse but rarely does the worst happen, and even more rarely on our honeymoons.

When you then read Warfield's comments of Romans 8:28 you know he speaks as one who has tested these words and found them true.
The fundamental thought is the universal government of God. All that comes to you is under His controlling hand. The secondary thought is the favour of God to those that love Him. If He governs all, then nothing but good can befall those to whom He would do good.... Though we are too weak to help ourselves and too blind to ask for what we need, and can only groan in unformed longings, He is the author in us of these very longings...and He will so govern all things that we shall reap only good from all that befalls us.
