Minister and give your life a ransome for many- A mark of a christian

Mark 10:42-45 KJV
But Jesus called them to him , and saith unto them, Ye know that they which are accounted to rule over the Gentiles exercise lordship over them; and their great ones exercise authority upon them. [43] But so shall it not be among you: but whosoever will be great among you, shall be your minister: [44] And whosoever of you will be the chiefest, shall be servant of all. [45] For even the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many.
