The sermon titled "Not Ashamed" (Part of the 'Living Godly Lives in the End Times' Series) by Gio focuses on living godly lives in the end times. It starts by emphasizing the importance of trusting in God despite the darkness of the world and the certainty that He will complete His good work in us. The sermon then highlights the individuality of salvation, using Noah, Daniel, and Job as examples of obedience, singleness of mind, and trust in God, even in difficult times. These qualities are described as proactive, deliberate choices made when grounded in God's Word.

Gio shares a personal story from high school to illustrate the concept of being ashamed of one's faith. He recalls a moment in a French class where a teacher asked students about their belief in the Biblical creation story, leading to a discussion on the concept of being ashamed of Jesus and His teachings. This concept is further explored through the examination of Mark 8:38, which warns that Jesus will be ashamed of those who are ashamed of Him.

The sermon emphasizes the cultural context of honor and shame during Jesus' time and its relevance today. Being ashamed of Christ, especially in a sinful and adulterous generation, is depicted as having eternal consequences. Gio stresses the need for Christians to be bold in their faith, regardless of ridicule or societal pressure.

Gio cites Clifford Goldstein’s book "The Day of The Dragon" which discusses the challenges Christians will face in the last days, including the temptation to abandon faith due to ridicule rather than persecution. The sermon underscores the importance of not being ashamed of any aspect of Christian faith, even those that may seem outdated or unpopular.

Paul's teachings in 2 Timothy 1 are referenced to emphasize the importance of standing firm in faith despite potential suffering or ridicule. Paul's example of not being ashamed of the gospel, despite his own imprisonment and suffering, is highlighted as a model for Christians.

Gio returns to his high school story, revealing that only one student, not himself, raised their hand in belief of the Biblical creation story. This moment of personal shame is compared to Peter's denial of Christ, emphasizing the importance of not repeating such mistakes.

The sermon concludes with a call to focus on Jesus, the "author and perfecter of faith," who endured the cross and despised its shame for humanity's sake. Gio urges the congregation to stand boldly for Christ, ensuring nothing, especially shame, separates them from their Savior. The sermon ends with a prayer for courage and growth in grace.
