for you to open the blind eyes, to bring forth out of the dungeon the prisoner, out of the house of detention those sitting in darkness.”​—Isaiah 42:6, 7.

15, 16. In what way did Jesus serve as “a light of the nations”?

¹⁵ As “a light of the nations,” the promised Servant will open “the blind eyes” and liberate “those sitting in darkness.” This Jesus did. By bearing witness to the truth, Jesus glorified the name of his heavenly Father. (John 17:4, 6) He laid bare religious falsehoods, preached the good news of the Kingdom, and opened the door to spiritual freedom for those in religious bondage. (Matthew 15:3-9; Luke 4:43; John 18:37) He warned against performing works that belong to darkness and exposed Satan as “the father of the lie” and “the ruler of this world.”​—John 3:19-21; 8:44; 16:11.

¹⁶ Jesus said: “I am the light of the world.” (John 8:12) He proved to be so in an outstanding way when he offered his perfect human life as a ransom. Thus he opened up the way for those who exercise faith to have forgiveness of sins, an approved relationship with God, and the prospect of eternal life. (Matthew 20:28; John 3:16) By maintaining perfect godly devotion throughout his life, Jesus upheld Jehovah’s sovereignty and proved the Devil a liar. Jesus truly was a giver of sight to the blind and a liberator of those imprisoned in spiritual darkness.
