In a sermon based on Acts 28:30-31, the speaker, Ian, argues that the unhindered gospel flourishes through suffering and disappointment. He shares personal anecdotes, including his family’s move from the Philippines to London, to illustrate how God's presence and grace sustain believers. The message concludes by inviting the audience to continue the story of Acts, emphasizing that the gospel is a living mission that finds a way to spread through everyday life and the actions of ordinary people.
