To begin, the book of Jonah, written by the prophet himself, transports us to the 8th century B.C., in a context where Israel faced the Assyrian threat. It narrates the singular story of Jonah, a prophet from the Northern Kingdom, who receives an unexpected divine command: to preach repentance to the feared city of Nineveh, capital of Assyria.

The narrative unfolds with Jonah's blatant disobedience, as he tries to flee from the presence of God. His incredible journey, marked by the storm and the experience in the belly of a great fish, demonstrates God's unquestionable sovereignty over all creation and the impossibility of escaping His will.

In the end, Jonah, reluctantly, fulfills his mission, and the unthinkable happens: the Ninevites deeply repent, and God demonstrates His unlimited mercy, which transcends ethnic and political barriers. The book, then, confronts the prophet's attitude, revealing the extent of divine love that extends to all peoples.

Crucially, Jesus Christ Himself validated and pointed to the truthfulness of this narrative, stating: "no sign will be given to them, except the sign of the prophet Jonah" (Matthew 12:39). The resurrection of Christ is prefigured in Jonah's experience, underlining the centrality of Christ and the universal mission of the gospel.

For the contemporary reader, Jonah is a powerful invitation to reflect on one's own compassion and obedience. It challenges us to overcome prejudices, embrace God's global mission and share the message of grace with everyone, reminding us that salvation comes from the Lord and that He cares for every life.
