Unexpected Lesson: Greatness is the DNA of Service. Jesus washed his disciples’ feet. There have been great men and women throughout history. There have been great deeds as well. But only One was able to take the ultimate insult of his time (washing feet!) and turn it into an image of everlasting greatness. Only Jesus could do that – embody greatness of service – because only Jesus is truly great. As for you and me, then, we must learn: One is not great because he serves; one serves because He is great.
