What does the Bible say about Jesus as the light of salvation?

In Isaiah 49:6, God declares that He will give Jesus as a light to the Gentiles, emphasizing that His salvation is for all people. Jesus Himself states in John 8:12, 'I am the light of the world.' This highlights how He illuminates the darkness of sin and ignorance, bringing life and understanding to those who believe in Him. The role of Jesus as the light indicates His purpose in revealing God's grace and mercy through salvation, showing that He is the only Savior for humanity at the end of the earth.
