Mark 16:12-16 ESV
After these things he appeared in another form to two of them, as they were walking into the country. And they went back and told the rest, but they did not believe them.
Afterward he appeared to the eleven themselves as they were reclining at table, and he rebuked them for their unbelief and hardness of heart, because they had not believed those who saw him after he had risen. And he said to them, “Go into all the world and proclaim the gospel to the whole creation. Whoever believes and is baptized will be saved, but whoever does not believe will be condemned.
