Jesus is talking about his Apostles here. Anyone that tells you God talks to him or that he hears God's voice is outright lying to you. The Apostles were endowed with these powers to prove to the people they came into contact with that what they were teaching was true. God doesn't act through people anymore, once the last Apostle died (John, if I recall correctly) that power passed from the Earth.Mark 16:17-18 King James Version (KJV)
17 And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;
18 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.
Mark 16:17-18 English Standard Version (ESV)
17 And these signs will accompany those who believe: in my name they will cast out demons; they will speak in new tongues; 18 they will pick up serpents with their hands; and if they drink any deadly poison, it will not hurt them; they will lay their hands on the sick, and they will recover.
I would like to suggest Ani-Freeze & Cobras..... Then you can heal one another with your magic hands.
The "healers" you see on t.v.(Benny Hinn, for example) are full of garbage.
