When Jesus washed His disciples' feet, this act of submission wasn't about showing off His superior humility or sensitivity. Setting an example wasn't even His primary motive.
Jesus knew that His time on earth was ending, and His heart was broken at the thoughts of leaving His friends. He wanted to love them one more time before He left.
Christ did the same for the rest of humankind, enduring the horrors of crucifixion as the ultimate manifestation of submission and as history's most wondrous act of sacrificial love.
Each one of us should do no less for our wife.
