Drawing from Luke 12:35-48, he highlights the importance of believers being prepared and watchful for Jesus' return rather than speculating about the exact timing. The focus is on living faithfully and obediently in anticipation of Jesus' return, as readiness and faithfulness are crucial when he comes back. The sermon concludes with a call to examine one's life and ensure it reflects a belief in Jesus' imminent return, urging repentance and embracing the gospel for readiness and faithfulness.
