We marvel at all of the amazing miracles that Jesus performed in the Bible. His life was filled with healing the sick, casting out demons, and raising the dead. We learn one of the biggest things that we are called to do from Jesus also. He calls us to a life of service for others.
Jesus gives us the best examples of this by his actions. Jesus fed people. It was a miracle that turned a few loaves of bread and a few fish into enough to feed thousands of people. However, Jesus didn't have to do this. He could have listened to his apostles and sent the people away to get food and rest but instead, he provided the food. He wanted to provide what the people needed.
Another act of service that Jesus performed was washing his friend's feet. To put this into context of the day, feet were dirty and dusty because they walked in sandals and through dusty lands. If you traveled everywhere by foot and in practically bare feet, your feet are bound to be dirty. He set the example of washing his disciples feet which was tending to the needs of someone else.
Feet were and are one of the dirtiest parts of the body. From the point of view of getting your feet washed, it's offering up a part of yourself that's very vulnerable. From the point of view of the one doing the washing, it's tending to a dirty and often overlooked part of someone. It is reaching down to help someone by putting yourself lower than anything else. No one was too good to wash someone else's feet.
Jesus showed us by these acts of service that we, too, are to do what we're able when we're able. Jesus taught us to put others above ourselves. He set the example of how we are to care for our fellow man, be it our brothers and sister or the stranger that we encounter.
