Why is Christ called our light, salvation, and life?

In Psalm 27, David asserts that 'the Lord is my light and my salvation.' This statement is profound because it lays the foundation of the believer's identity and hope in Christ. Christ as light signifies enlightenment, understanding, and guidance for our lives. As our salvation, He took upon Himself the punishment for our sin, ensuring that through faith in Him, we receive eternal life and forgiveness. Furthermore, the phrase 'the strength of my life' emphasizes that our true life is found in Christ alone. As believers, we are eternally connected to Him, receiving life not only now but also in the age to come.
