“Go therefore and make disciples of all the nations baptizing them in the name of the Father and of the Son and of the holy Spirit, teaching them to observe all things I have commanded you; and lo I am with you always, even to the end of the age.” Amen

Matthew 28:19-20 (NKJ)

“Go into all the world and preach the Good News to everyone.  Anyone who believes and is baptized will be saved.But anyone who refuses to believe will be condemned.These miraculous signs will accompany those who believe: They will Cast out demons in my name, and they will speak in new tongues.They will be able to handle snakes with safety, and if they drink anything poisonous, it won’t hurt them. They will be able to place their hands on the sick, and they will be healed.” 

And the disciples went everywhere and preached, and the Lord worked through them, confirming what they said by many miraculous signs. 

Mark 16:15-18, 20
