What does the Bible say about the eternal gospel?

The eternal gospel is described in 1 Peter 1:25, which affirms that the Word of the Lord endures forever. This gospel is eternal because it is rooted in the person and work of Jesus Christ, who was destined for this role before the foundation of the world. It is a message that transcends time and human change, reflecting God's unchanging plan for salvation. The gospel's eternal nature assures believers that their faith and hope in Christ will never perish, even as all earthly things fade away.
