But whosoever will be great among you, let him be your minister
By A.B. Simpson

      The first word here used for service is diakanos, which means minister to others in any usual way or work. The word doulos, however, means a bondservant, and the Lord here plainly teaches us that this is the highest form of service. Christ made himself the servant of all, and he who would come nearest to Him and stand closest to Him at last must likewise learn the spirit of the ministry that has utterly renounced selfish rights and claims forever. It is quite possible for us to be entirely loyal to the Lord Jesus, and yet for His sake to be servants and under the authority of those who are over us in the Lord. The doulos spirit is the spirit of self-renunciation and glad submission to proper authority-service utterly disinterested, yielding its own preferences and interests unreservedly for the glory of the Master and the sake of our brethren. Lord, clothe us with such humility and make us wholly Thine.
