The idea of one providing an example for another is very common in media. One of the greatest instances is Mr. Miyagi from The Karate Kid. Using his unorthodox methods, Mr. Miyagi teaches Daniel karate, but also shows the depth of Mr. Miyagi’s ability while taking on other challengers. In the servanthood of the cross, Jesus fights sin, death, and the devil, showing that he has the ability to do what needs to be done; in the footwashing of John 13, he is giving that example to his disciples.
