Passage
but not so shall it be among you; but whoever may will to become great among you, he shall be your minister,
but not so shall it be among you; but whoever may will to become great among you, he shall be your minister,
Mark 10:41 And the ten having heard, began to be much displeased at James and John,
Mark 10:42 but Jesus having called them near, saith to them, `Ye have known that they who are considered to rule the nations do exercise lordship over them, and their great ones do exercise authority upon them;
Mark 10:43 but not so shall it be among you; but whoever may will to become great among you, he shall be your minister,
Mark 10:44 and whoever of you may will to become first, he shall be servant of all;
Mark 10:45 for even the Son of Man came not to be ministered to, but to minister, and to give his life a ransom for many.'
The verse centers on "shall", "whoever", "become", "great", and "minister". It is saying that the verse draws attention to "shall" and "whoever", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 42's "but Jesus having called them near saith..." into verse 44's "and whoever of you may will to...", so "shall" and "whoever" belong inside that flow. In Mark context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "shall" and "whoever" with trust shaped by these words, not by a vague optimism outside the passage.
