In the Gospel of John chapter 13, Jesus girded Himself as a Servant.
One of the last lessons Jesus taught his disciples was how to serve one another.
He had put out a wash basin filled it with water and began to wash His disciples feet. He being their Lord and teacher showed them what extent a person that is following God must do to demonstrate what it means to humbly serve his fellow man.
Jesus teaches in the Beatitudes (Mathew Chapter 5) about going the extra mile or giving to those who need. The humility Jesus shows and asks from us is a deep spiritual revelation that every Christian should grow to understand. The example the bible shows also is reflected in the Apostle Paul's writings to the Philippians chapter 2:5:
Have this attitude in yourselves which was also in Christ Jesus, Who, although He existed in the form of God, did not regard equality with God a thing to be grasped, but emptied Himself, taking the form of a bond-servant, and being made in the likeness of men. Being found in appearance as a man, He humbled Himself by becoming obedient to the point of death, even death on a cross. NASB
Serving and following Jesus has never been an easy task. The hardest thing to do when serving Jesus has always been dying to self and taking up your cross. However in the process of dying to self, there is also the opportunity of receiving of the resurrecting power of the Holy Spirit that enables you to be obedient to the task that the Lord wishes you to serve and perform with excellence and joy.
