John 13:3-5 (NIV)
Jesus knew that the Father had put all things under his power, and that he had come from God and was returning to God; so he got up from the meal, took off his outer clothing, and wrapped a towel around his waist. After that, he poured water into a basin and began to wash his disciples’ feet, drying them with the towel that was wrapped around him.
He did not teach in the schoolroom manner the necessity of humility–He girded Himself with a towel and kneeled down and washed his disciples feet… He did not teach in a didactic way about the worth of children–He put his hands upon them and blessed them, and setting one in their midst tersely said, “Of such is the kingdom of God,” and He raised them from the dead. He did not argue the worth of womanhood and the necessity for giving them equal rights–he treated them with infinite respect, gave to them His most sublime teaching, and when He rose from the dead he appeared first to a woman. He did not prove how pain and sorrow in the universe could be compatible with the love of God–He took on Himself at the cross everything that spoke against the love of God, and through that pain and tragedy and sin showed the very love of God.
