Mark 16:17-18,20
“’And these signs will follow those who believe: In My name they will cast out demons; they will speak with new tongues; they will take up serpents; and if they drink anything deadly, it will by no means hurt them; they will lay hands on the sick, and they will recover.’ … And they went out and preached everywhere, the Lord working with them and confirming the word through the accompanying signs. Amen.”
Background
This little passage is in some translations of the New Testament, but not others. For more on that issue, see: Is This Scripture?
And these Signs
Mark’s first use of the word “sign” is in Mark 8:11-12 (see Do You Seek a Sign?). The root word in Greek translated as “sign” — σημεῖον (say-mi’-on) — means “a sign (typically miraculous), given especially to confirm, corroborate or authenticate. (It) emphasizes the end-purpose which exalts the one giving it. Accordingly, it is used dozens of times in the (New Testament) for what authenticates the Lord and His eternal purpose, especially by doing what mere man can not replicate (or) take credit for [1].”
Will Follow
The Greek word translated as “follow” here can also be translated as “accompany” [2,3] which is perhaps more clear. In other words (literally!), the first five words could be written as:
“And these signs will accompany”
Those Who Believe
In the context of Mark 16, “those who believe” are those who believe the gospel, i.e., those who have faith Jesus as the Christ, the Son of God.
In My Name
This means “in according with Jesus’ character, will, and purpose.” In other words, the listed signs would only occur in accord with Jesus’ will, not the will of those who believe in Him (see In His Name).
They will Cast Out Demons
It’s recorded that the apostle Paul cast out a demonic “spirit of divination” from a slave girl (Acts 16:16-18):
“Now it happened, as we went to prayer, that a certain slave girl possessed with a spirit of divination met us, who brought her masters much profit by fortune-telling. This girl followed Paul and us, and cried out, saying, ‘These men are the servants of the Most High God, who proclaim to us the way of salvation.’ And this she did for many days. But Paul, greatly annoyed, turned and said to the spirit, ‘I command you in the name of Jesus Christ to come out of her.’ And he came out that very hour.”
Notice what Paul said: “in the name of Jesus Christ … come out of her.” Paul cast out this demonic spirit in accord with the will and purpose of Jesus Christ. In fact, the apostle Paul was apparently even well known by the demonic spirits, who understood the true Authority behind him, and that simple use of the name of Jesus outside of faith in Him and His authority was of no value (Acts 19:13-16):
“Then some of the itinerant Jewish exorcists took it upon themselves to call the name of the Lord Jesus over those who had evil spirits, saying, ’We exorcise you by the Jesus whom Paul preaches.’ Also there were seven sons of Sceva, a Jewish chief priest, who did so. And the evil spirit answered and said, ‘Jesus I know, and Paul I know; but who are you?’ Then the man in whom the evil spirit was leaped on them, overpowered them, and prevailed against them, so that they fled out of that house naked and wounded.”
They will Speak with New Tongues
That is, they will speak with new intelligible languages (for more on this hotly debated issue of tongues see The Gift of Tongues). Perhaps the most dramatic example of this is the day of Pentecost (Acts 2:1-11):
“When the Day of Pentecost had fully come, they were all with one accord in one place. And suddenly there came a sound from heaven, as of a rushing mighty wind, and it filled the whole house where they were sitting. Then there appeared to them divided tongues, as of fire, and one sat upon each of them. And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit gave them utterance. And there were dwelling in Jerusalem Jews, devout men, from every nation under heaven. And when this sound occurred, the multitude came together, and were confused, because everyone heard them speak in his own language. Then they were all amazed and marveled, saying to one another, ‘Look, are not all these who speak Galileans? And how is it that we hear, each in our own language in which we were born? Parthians and Medes and Elamites, those dwelling in Mesopotamia, Judea and Cappadocia, Pontus and Asia, Phrygia and Pamphylia, Egypt and the parts of Libya adjoining Cyrene, visitors from Rome, both Jews and proselytes, Cretans and Arabs—we hear them speaking in our own tongues the wonderful works of God.’”
They will Take Up Serpents
It’s recorded that after a shipwreck on Malta the apostle Paul was bitten by a viper and suffered no ill effects, to the astonishment of those around him (Acts 28:1-6)!
If they Drink Anything Deadly
There’s no record in the New Testament of believers in Christ drinking poison and surviving [and if you’re tempted to do so, I exhort you not to do it!].
They will Lay Hands on the Sick
The book of Acts emphasizes many instances of healing by God through the apostle Paul. For example (Acts 19:11-12):
“Now God worked unusual miracles by the hands of Paul, so that even handkerchiefs or aprons were brought from his body to the sick, and the diseases left them and the evil spirits went out of them.”
And yes, there are specific instances of Paul literally laying hands on the sick too. For example (Acts 28:7-9):
“In that region there was an estate of the leading citizen of the island, whose name was Publius, who received us and entertained us courteously for three days. And it happened that the father of Publius lay sick of a fever and dysentery. Paul went in to him and prayed, and he laid his hands on him and healed him. So when this was done, the rest of those on the island who had diseases also came and were healed.”
The Word was Confirmed
This passage, indeed the Gospel of Mark, ends as follows:
“And they went out and preached everywhere, the Lord working with them and confirming the word through the accompanying signs. Amen.”
The meaning seems plain. That is, these miraculous signs had the purpose of “confirming the word” that was “preached everywhere” by the apostles and other early disciples.
Are these Signs for All Believers?
This is a question that has been debated for centuries, and it will not be resolved here. However, in brief, it’s the opinion of this author that these sign were descriptive, not prescriptive, and primarily for the apostles and perhaps some other disciples during the “apostolic age” in accord with the will and purpose of God in order to confirm and authenticate the apostles’ teaching as part of establishing the Church prior to the completion and distribution of the New Testament writings. However, it is also the opinion of this author that God can will for any Christian to exhibit a sign (it just isn’t a “normative” experience). For more on that, see the series entitled Spiritual Gifts.
Application
If you are believer in Jesus Christ, then you should “always be ready to give a defense to everyone who asks you a reason for the hope that is in you (1 Peter 3:15).” And that defense should always be rooted in the word of God. Therefore, pray that the Lord would accompany your sharing of the word with “something” that confirms the truth of the word to the hearer(s). He may or may not choose to answer that prayer in a way that you desire or expect; however, He may work through that circumstance to confirm His word in a way that you may or may not perceive. Regardless, to Him be the glory!
