The sermon centers on the imperative to remain unashamed of the gospel and its messenger, even in the face of persecution or social pressure, drawing from Paul's final exhortation to Timothy. It emphasizes that the gospel's power—rooted in God's eternal purpose, grace, and the redemptive work of Christ—is not only the source of salvation but also the foundation for bold witness, as Christ has abolished death's sting and revealed eternal life and immortality. Ultimately, the message is a call to glory in the gospel, and to be faithful witnesses in a world that often rejects it.
