Lk 2:28-32, Mt 11:2-5, Acts 26:22-23

In the Old Testament, God said that He would establish Christ to be the covenant of Israel and the light of the Gentiles. (Isa 42:6-9)

Isa 42:6 I the Lord have called thee in righteousness, and will hold thine hand, and will keep thee, and give thee for a covenant of the people, for a light of the Gentiles; 7 To open the blind eyes, to bring out the prisoners from the prison, and them that sit in darkness out of the prison house. 8 I am the Lord: that is my name: and my glory will I not give to another, neither my praise to graven images. 9 Behold, the former things are come to pass, and new things do I declare: before they spring forth I tell you of them.

Simeon embraced the baby Jesus and confessed that this Jesus was the light to the Gentiles and the glory of Israel. (Luke 2:28-32)

Luke 2:28 Then took he him up in his arms, and blessed God, and said, 29 Lord, now lettest thou thy servant depart in peace, according to thy word: 30 For mine eyes have seen thy salvation, 31 Which thou hast prepared before the face of all people; 32 A light to lighten the Gentiles, and the glory of thy people Israel.

Jesus is the Christ who heals us as prophesied in the Old Testament. (Matthew 11:2-5)

Matthew 11:2 Now when John had heard in the prison the works of Christ, he sent two of his disciples, 3 And said unto him, Art thou he that should come, or do we look for another? 4 Jesus answered and said unto them, Go and shew John again those things which ye do hear and see: 5 The blind receive their sight, and the lame walk, the lepers are cleansed, and the deaf hear, the dead are raised up, and the poor have the gospel preached to them.

Paul testified to the Jews that Jesus was the Christ who prophesied the light to Israel and the Gentiles prophesied in the Old Testament. (Acts 26:22-23)

Acts 26:22 Having therefore obtained help of God, I continue unto this day, witnessing both to small and great, saying none other things than those which the prophets and Moses did say should come: 23 That Christ should suffer, and that he should be the first that should rise from the dead, and should shew light unto the people, and to the Gentiles.
