But he answered and said unto them, 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:

Historical Context
Calling Israel 'adulterous generation' has Old Testament roots: prophets consistently used marriage/adultery imagery for covenant relationship. Hosea married prostitute symbolizing Israel's spiritual adultery (Hosea 1-3). Jeremiah accused Judah of adultery (Jeremiah 3:6-10). Ezekiel 16 and 23 contain extended metaphors of Jerusalem/Samaria as unfaithful wives. Jesus applies this to His generation: despite covenant relationship, they rejected Messiah. The request for sign echoes Numbers 14:11: 'How long...will they not believe me, for all the signs which I have shewed among them?' Same pattern: abundant evidence rejected, more signs demanded. Jonah's sign would be Jesus's three days in heart of earth (death/burial) followed by resurrection—ultimate vindication. Yet even resurrection was rejected by authorities (Matthew 28:11-15). Paul later writes: Jews demand signs, Greeks seek wisdom, but we preach Christ crucified (1 Corinthians 1:22-23)—gospel offense to both groups. Church history confirms: resurrection is sufficient sign for those with eyes to see, insufficient for hardened hearts.

- Why is resurrection the ultimate sign—what makes it sufficient evidence for those willing to believe?
- How do you avoid the pattern of demanding more evidence while dismissing what God has already revealed?

Analysis & Commentary
'But he answered and said unto them, 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.' Jesus refuses their demand, calling them 'evil and adulterous generation' (γενεὰ πονηρὰ καὶ μοιχαλίς/genea ponēra kai moichalis). The phrase 'adulterous' metaphorically describes spiritual unfaithfulness—Israel was God's bride (Hosea 1-3), now unfaithful through unbelief and rejection of Messiah. Reformed theology sees 'sign-seeking' as symptom of evil: demanding proof while rejecting evidence reveals hardened hearts. Jesus promises only one sign: 'sign of prophet Jonas' (τὸ σημεῖον Ἰωνᾶ τοῦ προφήτου/to sēmeion Iōna tou prophētou)—explained in v.40 as death and resurrection. This is ultimate sign: resurrection validates Christ's claims definitively. Yet many rejected even this (Matthew 28:11-15). The verse warns: those demanding signs often reject them when given. It also shows Jesus's authority: He doesn't submit to their demands but determines what evidence He'll provide.
