The fourth man in the furnace was an angel sent by Jehovah, not a symbol or preincarnate Christ, as Daniel 3:28 explicitly explains.
DANIEL 3:25 — Who Was the Fourth Man in the Furnace? An Angel, the Preincarnate Christ, or a Symbolic Figure?
DANIEL 3:16–18 — Did Shadrach, Meshach, and Abednego Show Presumption by Expecting Deliverance From the Furnace?
Shadrach, Meshach, and Abednego did not presume deliverance; they trusted God’s power while submitting to His will, even if death followed.
