Everyone?

[Bowas]

In the following verses, it is widely taught that this verse, mandates all must be baptize or they will be damned. No real dispute there.

In the next verses, it also shows what will be signs of those that believe from casting out devils, speaking in new tongues, taking up seprents, drinking deadly things, and laying on of hands for the sick to recover.

Here is point of this post.
Using this verse as a mandate for all believers to speak in tongues, to be consistent with that interpretation, then every believer must also do the other signs.
One moght say, "Well, the believers have the ability to cast our devils etc, but do not have to as requirement as tongues are.

Thoughts? (I have my thoughts, but curious on how others address this)

Mar 16:15.. And he said unto them, Go ye into all the world, and preach the gospel to every creature...
Mar 16:16.. He that believeth and is baptized shall be saved; but he that believeth not shall be damned...
Mar 16:17.. And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;..
Mar 16:18.. 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.
