Mark 16:15-20

MLV(i) 15 And he said to them, When you travel into all the world, preach the good-news to all creation. 16 He who believes and is immersed will be saved, but he who disbelieves will be condemned.
17 Now these signs will be following those who have believed: they will be casting out demons in my name; they will be speaking in new languages; 18 they will be lifting up serpents and even if they drink anything deadly, it may never harm them; they will lay hands upon the sick and they will be well.

{Luk 24:44-49 & Acts 1:3-8 & 1Co 15:7 Jerusalem.}

19 Therefore indeed, the Lord, after he had spoken to them, was received up into heaven and sat down at the right hand of God. 20 Now those apostles went forth and preached everywhere, the Lord working together with them, and confirming the word through the signs that followed. Amen.
