Afterward he appeared unto the eleven as they sat at table, and rebuked them for their unbelief and hardness of heart, because they believed not them who had seen him after he was risen. And he said unto them, Go you into all the world, and preach the gospel to every creature. He that believes and is baptized shall be saved; but he that believes not shall be condemned. read more.
And these signs shall follow them that believe; In my name shall they cast out demons; they shall speak with new tongues; They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover.

Behold my hands and my feet, that it is I myself: handle me, and see; for a spirit has not flesh and bones, as you see me have. And when he had thus spoken, he showed them his hands and his feet. And while they yet believed not for joy, and wondered, he said unto them, Have you here any food? And they gave him a piece of a broiled fish, and a honeycomb. And he took it, and did eat before them. And he said unto them, These are the words which I spoke unto you, while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me. Then opened he their understanding, that they might understand the scriptures, And said unto them, Thus it is written, and thus it was fit for Christ to suffer, and to rise from the dead the third day: And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem. And you are witnesses of these things. And, behold, I send the promise of my Father upon you: but tarry you in the city of Jerusalem, until you are endued with power from on high.
