These are all examples of what Christ would do. In fact, if we are filled with Him when we serve, we are like little Christs, like tiny lights reflecting the grand Light of the World in a dark and needy land.
When Jesus washed his disciples' feet, he was teaching them what the Father values and what is very common in heaven: Serving others! To serve with joy is to reproduce a heavenly activity here on earth. What a privilege it is to be a Christian!
(John 13:15)
