What does the Bible say about the nature of the Gospel?

The Gospel is fundamentally about the person of Jesus Christ. As emphasized in Acts, it is a declaration of the good news of a resurrected, reigning King who came with sovereign, eternal purposes to offer salvation to sinners. This Gospel is richly rooted in the Scriptures, from the Law and the Prophets through to the New Testament, revealing God's consistent plan for redemption through Christ. In John 17, Jesus shows His authority, stating that He has power over all flesh to grant eternal life to those given to Him. Thus, the Gospel is not merely a set of doctrines; it is about knowing the only true God and Jesus Christ whom He has sent, reflecting on His glory and infinite aspects.
