Alzheimer's disease is never an 'accident' in a marriage. It falls under the purview of God's sovereignty. In the case of someone with Alzheimer's, this means God's unconditional and sacrificial love has an opportunity to be even more gloriously displayed in a life together.

The soul that has come to know God fully no longer desires anything else, nor does it attach itself to anything on the earth; and if you put before it a kingdom, it would not desire it, for the love of God gives such sweetness and joy to the soul that even the life of a king can no longer give it any sweetness.
