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

If you’re not sure, here are a few common requests and the typical evangelical view of the most likely author for each (briefly):

– Pentateuch (Genesis–Deuteronomy): Evangelicals traditionally attribute these to Moses (with recognition that literary development/redaction may have occurred). Support comes from internal claims and long-standing Jewish/Christian tradition.
– Psalms: Many psalms are attributed to David (esp. the superscribed ones); others are linked to Asaph, the sons of Korah, Solomon, etc.
– Proverbs: Largely attributed to Solomon (with collections from other wise men).
– Isaiah: Traditionally attributed to the prophet Isaiah (some evangelicals accept single authorship; others allow for a later redaction but still hold Isaiah as principal author).
– Jeremiah/Ezekiel/Hosea, etc.: Attributed to the prophets whose names head the books.
– The Gospels: Matthew (the tax collector and apostle), Mark (John Mark, companion of Peter), Luke (Luke the physician and companion of Paul), John (the apostle John). Evangelicals typically affirm these traditional attributions, especially for eyewitness or apostolic connection.
– Acts and Luke: Luke is traditionally seen as the author of Luke–Acts (Luke, companion of Paul).
– Paul’s Epistles: Romans, 1–2 Corinthians, Galatians, Philippians, 1 Thessalonians, Philemon, etc., are attributed to Paul (widely affirmed by evangelicals). Some epistles (e.g., Ephesians, Colossians, 2 Thessalonians, Pastoral Epistles) have more debate but many evangelicals still accept Pauline authorship or at least Pauline origin.
– Hebrews: More debated; historic attributions to Paul were common, but many evangelicals today accept unknown authorship or consider Barnabas, Apollos, or Luke as possibilities while still treating the book as authoritative.
– John’s letters and Revelation: 1–3 John and the Gospel often attributed to the apostle John; Revelation traditionally to John the apostle (some evangelicals affirm this, others debate the precise identity).

If you tell me which book you meant, I can give a focused evangelical perspective on the most-likely author: historical evidence, internal clues, early church testimony, theological reasons, and why some questions remain.
