Yes that is true… But would you not say that since the Bible is inspired by God that he has given us enough within the scriptures to know about him? He has given us enough to understand how he created things even though we can’t fully understand it all, he has given us his ways, what he dislikes and likes, what he hates and what he loves, we know God cares for us, we know his always there for us… All this we know because it is written down. And yes he even told us what kind of worship he accepts and what he doesn’t accept example idol worship… So I think the Bible does have all the answers
Just out of interest sake The NWT is not the only Bible to render John 1:1c as “a god”. Actually, there are many Bibles that render John 1:1 as “a God” or it’s equivalent and some of them being much older than the NWT here’s a few:
1808: “and the word was a god.” The New Testament in an Improved Version, Upon the Basis of Archbishop Newcome’s New Translation: With a Corrected Text.
1864: “and a god was the word.” The Emphatic Diaglott, interlinear reading, by Benjamin Wilson.
1928: “and the Word was a divine being.” La Bible du Centenaire, L’Evangile selon Jean, by Maurice Goguel.
1935: “and the Word was divine.” The Bible—An American Translation, by J. M. P. Smith and E. J. Goodspeed.
1946: “and of a divine kind was the Word.” Das Neue Testament, by Ludwig Thimme.
1958: “and the Word was a God.” The New Testament, by James L. Tomanek.
1975: “and a god (or, of a divine kind) was the Word.” Das Evangelium nach Johannes, by Siegfried Schulz.
Even Origen, the most knowledgeable of the early Christian Greek-speaking scholars, tells us that John 1:1c actually means “the Word [logos] was a god”. - “Origen’s Commentary on John,” Book I, ch. 42 - Bk II, ch.3.
Origen’s Commentary on John is “the first great work of Christian interpretation.” Origen was certainly the most knowledgeable about NT (koine) Greek of any scholar. He studied it from early childhood and even taught it professionally from his teens onward. And this was during a time when it was a living language and, of course, well understood. - The Ante-Nicene Fathers, pp. 291-294, vol. X, Eerdmans Publ., 1990 printing.
Greek grammar and the context strongly indicate that the New World Translation rendering is correct and that “the Word” should not be identified as the “God”… Please do some research about what Origin said and other greek scholars here’s a link:
