G.W. North emphasizes the significance of the resurrection of Jesus Christ in his sermon 'By the Resurrection From the Dead.' He explains that while the Romans were unfamiliar with Jewish traditions, the resurrection was a groundbreaking event that proved Jesus to be the Son of God with power. North highlights that the resurrection was essential for the gospel, as it validated the effectiveness of the cross and confirmed Jesus' identity as the Savior. He argues that without the resurrection, there would be no gospel, and it was this event that sparked the growth of the early church, even in Rome. Ultimately, the resurrection serves as God's public testimony of Jesus' perfection and divinity, assuring believers of the truth of the gospel.
