Passage
And He said to them, “Go into all the world and preach the gospel to all creation.
And He said to them, “Go into all the world and preach the gospel to all creation.
Mark 16:13 And they went away and reported it to the others, but they did not believe them either.
Mark 16:14 Afterward He appeared to the eleven themselves as they were reclining at the table; and He reproached them for their unbelief and hardness of heart, because they had not believed those who had seen Him after He had risen.
Mark 16:15 And He said to them, “Go into all the world and preach the gospel to all creation.
Mark 16:16 He who has believed and has been baptized shall be saved; but he who has disbelieved shall be condemned.
Mark 16:17 And these signs will accompany those who have believed: in My name they will cast out demons, they will speak with new tongues;
The verse centers on "world", "said", "preach", "gospel", and "creation". It is saying that the verse draws attention to "world" and "said", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 14's "Afterward He appeared to the eleven themselves..." into verse 16's "He who has believed and has been...", so "world" and "said" 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 "world" and "said" with trust shaped by these words, not by a vague optimism outside the passage.
