Mark 16:15-18

Go unto 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 damned. And these signs shall follow them that believe. In my name shall they cast out devils. 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.

John 20:27-29

...Reach your finger here and behold My hands; and reach your hand here and thrust it into My side; and do not be unbelieving, but believing. ...Thomas, because you have seen Me you have believed. Blessed are they who have not seen and have believed.

Matthew 28:18-20

All power is given unto me in heaven and in earth. Go therefore and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost; teaching them to observe all things that I have commanded you. I am with you always, even unto the end of the world.
