Is bible study essential for Christian faith? yes, especially if a person can read and write.
Do you need denomination to find hope in Christ? no.
A couple of denominations that are dedicated to bible study and living the word in this wicked world:
https://www.adventist.org/en/. do a search for a local church near your area.
http://www.fundamental.org/fundamental/churches/. Do a search for a local church in your area.
Of course, you do not have to be a member to appreciate the strengths in these denominations or church groups. Each group has different strengths.
These denominations are dedicated to helping people overcome bondage and burden in life.
The far left hates bible study, so you may find websites directing you away from these denominations.... study with the people.... anyway.
Yes, there are other good church groups available. Messianic, Mennonite and so forth..... but for the general person, these two denominations can be a good start in walk of faith. Right now I only list these two denominations for this particular blog posting.
