Mark 16:14-20 - Jesus Talks To The Apostles
14 Finally he appeared unto the eleven as they sat at the table and upbraided them for their unbelief and hardness of heart because they did not believe those who had seen him after he was risen. 15 And he said unto them, Go ye into all the world and preach the gospel to every creature. 16 He that believes and is baptized shall be saved, but he that believes not shall be condemned. 17 And these signs shall follow those that believe: In my name they shall cast out demons; they shall speak with new tongues; 18 they shall take away serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands upon the sick, and they shall be healed.
19 So then after the Lord had spoken unto them, he was received up into heaven and sat at the right hand of God. 20 And they, going forth, preached everywhere, the Lord working with them and confirming the word with the signs which followed them. Amen.
