What does the Bible say about the importance of preaching Jesus?

In Scripture, specifically in Acts 8, we see Philip preaching Jesus as the core of his message. He opened his mouth and began at the same scripture, preaching to the Ethiopian eunuch about Christ. This highlights the importance of preaching Jesus, as he is the fulfillment of God's promise of salvation to humanity. The Apostle Paul further underscores this in Romans 1:1-3, where he states that the gospel is concerning God's Son, Jesus Christ our Lord. This connection within scripture establishes that the message of the gospel is not merely a set of doctrines, but rather a personal relationship with Jesus, who is central to salvation and eternal life.
