The speaker compares historical and modern advancements, like Roman roads and 5G, to underscore that while these innovations are significant, they are not as crucial as Jesus Christ. Emphasizing that Jesus is God's ultimate "big thing," the speaker argues that despite human achievements, God's plan centers on Jesus, who divides history and offers salvation. Using the story of Philip and the Ethiopian eunuch from Acts 8, the speaker illustrates that all innovations and paths ultimately lead to Jesus. The message challenges listeners to prioritize Jesus in their lives, recognizing Him as the true focus of God's purpose.
