I’m missing the book name in your question — could you tell me which Bible book you mean?

If it helps, here’s a short menu of common books and who most evangelical Christians consider the most-likely author (with a one-sentence note about the view):

– Genesis, Exodus, Leviticus, Numbers, Deuteronomy — Moses (evangelicals typically affirm Mosaic authorship while recognizing some editorial activity).
– Joshua — Joshua (often seen as written by/under Joshua or by later tradition).
– Judges, Ruth, 1–2 Samuel, 1–2 Kings — traditionally attributed to Samuel, Nathan, Gad, and later prophetic historians; evangelicals accept early prophetic sources compiled into the histories.
– 1–2 Chronicles, Ezra, Nehemiah — Ezra/Nehemiah and chronicler tradition (postexilic compiler).
– Isaiah — Isaiah the prophet (many evangelicals favor single-author Isaiah, though some acknowledge later expansion).
– Jeremiah — Jeremiah (with Baruch as secretary/scribe).
– Ezekiel — Ezekiel.
– Daniel — Daniel (evangelicals usually affirm Daniel’s authorship and historical setting).
– Psalms — David is the principal author of many psalms; other authors include Asaph, the Sons of Korah, Solomon, Moses, etc.
– Proverbs, Song of Solomon, Ecclesiastes — Solomon (evangelicals commonly accept Solomonic authorship, though Ecclesiastes uses the title “Qoheleth”).
– Major and Minor Prophets — attributed to the named prophets (Hosea through Malachi).
– Matthew — Matthew the tax collector/apostle.
– Mark — John Mark (traditionally writing Peter’s recollections).
– Luke — Luke the physician (companion of Paul); also author of Acts.
– John (Gospel) and 1–3 John — John the Apostle (evangelicals commonly affirm Johannine authorship).
– Acts — Luke.
– Romans, 1–2 Corinthians, Galatians, Philippians, 1 Thessalonians, Philemon — Paul (widely accepted by evangelicals as Paul’s letters).
– Ephesians, Colossians, 2 Thessalonians — Paul is traditionally credited, though some evangelicals discuss debated letters and still often accept Pauline authorship or defend authenticity.
– 1–2 Timothy, Titus — pastoral epistles: many evangelicals affirm Pauline authorship, though some engage the scholarly debate.
– Hebrews — historically debated; many older evangelical traditions attributed it to Paul, but many contemporary evangelicals acknowledge the author is anonymous and offer candidates (Barnabas, Apollos, Luke) while retaining the book’s authority.
– James — James the brother of Jesus (leader in Jerusalem).
– 1–2 Peter — Peter the Apostle (with acknowledgement of some scholarly debate about style).
– Jude — Jude, brother of Jesus.
– Revelation — John the Apostle/John of Patmos (evangelicals commonly affirm apostolic authorship).

If you tell me which book you meant, I can give a fuller evangelical perspective on its authorship, supporting evidence, and common objections.
