I just saw this on Pinterest...

From what I can tell from the website - this woman is washing her husbands feet as a commitment to serve him...
Can someone please explain this to me? I know in my ceremony, the pastor mentioned trying to out love each other and out serve each other...but if he had told me I had to wash my H's feet in a wedding dress I would have laughed in his face. Shiit, if he had told me I had to wash his feet at all I would have laughed in his face.
Someone explain this to me....PLEASE.
