Where did you get that quote? I wish you'd quote correctly. Here's why...
Saved from what? Why does it say those who believe not shall be damned. It doesn't say those who are not baptized will be damned.
Mark 16:15-17
15 And he said unto them, Go ye into all the world, and preach the gospel to every creature. 16 He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
You're smart enough to figure out how Jesus' words are not true for YOU. Can you cast out devils, and speak with new tongues?
Mark 16:17 And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;
Can you pick up poisonous serpents, and drink any deadly thing and not be hurt?
Mark 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.
Sounds like signs and wonders to me. Paul had those for awhile, but they ceased. Why is that?
