Pastor Johnathan begins his sermon series on the prophetic book of Nahum, focusing on God's judgment against Nineveh and the Assyrian empire. This first message argues that understanding this ancient history provides crucial insight into the present-day wickedness of the world and the necessity of recognizing God's righteous judgment, ultimately pointing to the beauty and power of the gospel. He urges any listening to embrace repentance and believe in the face of cultural decline and to find comfort in God's ultimate triumph over evil.
