What does the Bible say about the gospel in Isaiah?

Isaiah 53 is a foundational text in understanding the gospel as it foretells the coming of the Messiah, Jesus Christ, who would be despised and rejected. This passage outlines how He bore our griefs and carried our sorrows, and was wounded for our transgressions. The chapter emphasizes God's justice and the profound truth that through Christ's sacrifice, God's righteousness is declared while justifying those who believe in Him. The gospel revealed in Isaiah shows the unchanging nature of God and the need for a perfect Savior, affirming that true salvation is solely through Jesus.
