As God adds his 'Yes' to your 'Yes,' as he confirms your will with his will, and as he allows you, and approves of, your triumph and rejoicing and pride, he makes you at the same time instruments of his will and purpose both for yourselves and for others. In his unfathomable condescension God does add his 'Yes' to yours; but by doing so, he creates out of your love something quite new - the holy estate of matrimony.
