What does the Bible say about belief in the gospel?

In Isaiah 53, the opening question, 'Who hath believed our report?' highlights the necessity of believing in the message of the gospel. This belief is not merely about accepting historical facts, but it involves a deep trust in the Lord Jesus Christ Himself. Just as Abraham believed God and what He promised, we too must put our faith in Him and what He has done for us. The gospel is a call to faith in the person of Christ, who is the embodiment of the message God has given to humanity.
