Passage
And they went and told it unto the residue: neither believed they them.
And they went and told it unto the residue: neither believed they them.
Mark 16:11 And they, when they had heard that he was alive, and had been seen of her, believed not.
Mark 16:12 After that he appeared in another form unto two of them, as they walked, and went into the country.
Mark 16:13 And they went and told it unto the residue: neither believed they them.
Mark 16:14 Afterward he appeared unto the eleven as they sat at meat, and upbraided them with their unbelief and hardness of heart, because they believed not them which had seen him after he was risen.
Mark 16:15 And he said unto them, Go ye into all the world, and preach the gospel to every creature.
The verse centers on "went", "told", "residue", "neither", and "believed". It is saying that the verse draws attention to "went" and "told", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 12's "After that he appeared in another form..." into verse 14's "Afterward he appeared unto the eleven as...", so "went" and "told" 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 "went" and "told" with trust shaped by these words, not by a vague optimism outside the passage.
