Passage
And they, when they had heard that he was alive, and had been seen of her, believed not.
And they, when they had heard that he was alive, and had been seen of her, believed not.
Mark 16:9 Now when Jesus was risen early the first day of the week, he appeared first to Mary Magdalene, out of whom he had cast seven devils.
Mark 16:10 And she went and told them that had been with him, as they mourned and wept.
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.
The verse centers on "heard", "alive", "been", "seen", and "believed". It is saying that the verse draws attention to "heard" and "alive", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 10's "And she went and told them that..." into verse 12's "After that he appeared in another form...", so "heard" and "alive" 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 "heard" and "alive" with trust shaped by these words, not by a vague optimism outside the passage.
