“Whoever wants to be a leader among you must be your servant, and whoever wants to be first among you must become your slave” (Matthew 20:26-27, NLT).
Jesus told His disciples in private of His impending death and resurrection. In Matthew each prediction of Jesus’ suffering is connected to instruction about discipleship in light of suffering.
After the private meeting with His disciples, the mother of James and John came to Jesus and requested that her sons sit at Jesus’ right and left hands in His Kingdom. Jesus replied that was a decision made by the Heavenly Father.
When the other disciples heard of the request, they were indignant and probably argued among themselves. Jesus then called them together and defined the primary qualification for leadership in His Kingdom: a leader must be a servant.
