Go preach the gospel!
David Jacobs
The book of Mark was written the shortest length of time from Jesus' death out of all the Gospels. The other Gospels are written with more style and flair, perhaps because they had heard the same stories as Mark but several decades later. The gospel of John, in particular, is filled with tales of the supernatural that are not written about at all in Mark. The gospel of Mark is perhaps the least cited and considered the least important of the gospels by many, but the no-frills attached writing style and seemingly more accurate depiction of Christ makes it my favorite.
In these verses, Christ commands the disciples to do two things: first, go into the world and preach the gospel to every creature. As we know based on the book of Acts and most of the books following the gospels, the disciples took this commandment to heart. Second, everyone that is baptized will be saved, and those that are not shall be damned. Christ may have meant that any person that is not literally baptized is damned, but I think that a more progressive interpretation is more appropriate.

All that know of the gospels, and almost all should because the disciples went forth and spread the good news to all creatures, have a choice: to believe or not to believe. If they have heard the news and chose not to believe, they are refusing the baptism by the Holy Spirit. There is no supernatural element, no poetic prose, just the straight facts of the gospel of Mark. We should all appreciate his work. Thanks be to God.
