The power to be immune to all forms of poisons.

These are some of the signs that will accompany believers: They will throw out demons in my name, they will speak in new tongues, they will take snakes in their hands, they will drink poison and not be hurt, they will lay hands on the sick and make them well.” Mark 16:17,18 The Message

The promise of protection from poisonous snakes is not new in the New Testament. David talked about it on Psalms 91 " You will trample down lions and snakes, fierce lions and poisonous snakes."
