Your icon says you’re a member of the United Methodist Church. That’s a mainline denomination, meaning that they accept critical scholarship. In that case the major translations are, from least to most literal:
* Good News Bible
* Revised English Bible
* Common English Bible [CEB and REB are probably about equivalent in how literal they are]
* New Revised Standard Version
Of these, the REB didn’t sell well, and not many editions are still in print, though it’s a fine translation.
The other translations are not necessarily a “step up” from the Good News Bible. I consider the Good News Bible one of the most accurate translations out there. It’s just “meaning for meaning” rather than “word for word.” If you want to read a section for personal reflection, I would still use it.
However if you’re trying to understand a passage in detail, you want one of the others. For that the NRSV is the usual recommendation. Scholars and college courses in mainline and secular schools normally use it.
The CEB and REB are possible compromises. They're easier to read than the NRSV but still more literal than the Good News Translation. However but I have some reservations about the reliability of the CEB, so I’m no longer recommending it, though I use it in Sunday School. I don’t have the same reservations about the REB, but it’s become uncommon enough that you won’t find many others in your church using it. It’s easier to understand than the NRSV, but not as free as the Good News Translation. So it may be a good compromise.
If you don’t have a solid background, you might want to get a version with annotations. That will give you the historical background of each book as a whole, and also of specific passages. I think at this point I’d suggest the Harper Collins Study Bible, which uses the NRSV. College courses often use this or the New Oxford Annotated Bible, also NRSV, but the notes for New Oxford are briefer, and may not be as helpful. Note that the Harper Collins Study Bible is a bit more visible in using modern critical scholarship. This is what is being taught in United Methodist seminaries, but many laypeople may find the approach unsettling. I'd recommend it for any of our church members, but I don't know you.
There’s also a nice edition for young adults, “The Guidebook: The NRSV Student Bible.” Use it (if you can find it — it seems to be going out of print) if you don’t want the amount of information in the two mentioned above but still want some guidance. This isn't a children's Bible. No cute comic characters. (I'm thinking of the CEB Deep Blue Kids Bible, which would be appropriate for high school students if it didn't have all those comic characters. If I were a 10 year-old I'd consider that condescending, but I don't know kids that age as well as older ones.)
There’s also an annotated edition of the REB, the Oxford Study Bible. I have the same reservations about it that I do about the New Oxford Annotated: it does give you the historical information you need to understand what’s going on, but the notes are significantly terser than those in the Harper Collins Study Bible. However you may find the REB easier to read than NRSV.
