Mark 16:14Afterward he appeared to the eleven as they sat at meat, and upbraided them with their unbelief and hardness of heart, because they believed not them which had seen him after he was risen. 15And he said to them, Go you into all the world, and preach the gospel to every creature. 16He that believes and is baptized shall be saved; but he that believes not shall be damned.
Matthew 28:19 Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.”
