📖 Biblical Definition
When the scribes and Pharisees demanded a miraculous sign from Jesus, He refused their demand and pointed to Jonah: "For as Jonas was three days and three nights in the whale's belly; so shall the Son of man be three days and three nights in the heart of the earth" (Matthew 12:40). The sign of Jonah is a prophetic type of Christ's resurrection. Just as Jonah was swallowed by death and brought back to life, so Christ would descend into the grave and rise again on the third day. Furthermore, Jonah's preaching brought repentance to pagan Nineveh — a foreshadowing of the gospel going to the Gentiles. Jesus declared that the men of Nineveh would condemn the generation that rejected Him, "because they repented at the preaching of Jonas; and, behold, a greater than Jonas is here" (Matthew 12:41).

SIGN, n. [L. signum.] A token; something by which another thing is shown or represented. In theology, a miracle; a wonder; a remarkable event indicating the divine will. Webster understood signs as God-given evidence pointing to divine truth — not arbitrary wonders performed on demand, but sovereign acts revealing God's purpose in history.
📖 Key Scripture
• Matthew 12:39-41 — "An evil and adulterous generation seeketh after a sign; and there shall no sign be given to it, but the sign of the prophet Jonas."
• Jonah 1:17 — "Now the LORD had prepared a great fish to swallow up Jonah. And Jonah was in the belly of the fish three days and three nights."
• Jonah 2:10 — "And the LORD spake unto the fish, and it vomited out Jonah upon the dry land."
• Luke 11:30 — "For as Jonas was a sign unto the Ninevites, so shall also the Son of man be to this generation."
⚠️ Modern Corruption
The sign of Jonah is dismissed as myth, and the demand for signs continues unabated.

Liberal scholarship treats Jonah as allegory or fiction, stripping the sign of its typological power. If Jonah's three days in the fish never happened, then Jesus either lied or was mistaken — both of which destroy His authority. Meanwhile, the charismatic sign-seeking culture perpetuates the very error Jesus condemned: demanding spectacular signs rather than believing the testimony of Scripture. The greatest sign has already been given — the resurrection. Those who refuse the sign of Jonah would not believe even if someone rose from the dead (Luke 16:31).
Usage
• "Jesus gave one sign to the sign-seekers: the sign of Jonah — His own death and resurrection. No further proof is owed to unbelief."
• "Jonah in the belly of the fish prefigured Christ in the tomb — swallowed by death, yet delivered by the sovereign power of God."
