Lk 4:16-21, Mt 11:3-5, Lk 7:21-22, Acts 10:38

In the Old Testament, Isaiah prophesied that the Spirit of God would come upon Christ and preach the gospel of salvation from Christ. (Isa 61:1-2)

Isa 61:1 The Spirit of the Lord God is upon me; because the Lord hath anointed me to preach good tidings unto the meek; he hath sent me to bind up the brokenhearted, to proclaim liberty to the captives, and the opening of the prison to them that are bound; 2 To proclaim the acceptable year of the Lord, and the day of vengeance of our God; to comfort all that mourn;

Jesus testified that the prophecies prophesied by Isaiah in the Old Testament had been fulfilled in Himself. (Luke 4:16-21)

Luke 4:16 And he came to Nazareth, where he had been brought up: and, as his custom was, he went into the synagogue on the sabbath day, and stood up for to read. 17 And there was delivered unto him the book of the prophet Esaias. And when he had opened the book, he found the place where it was written, 18 The Spirit of the Lord is upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised, 19 To preach the acceptable year of the Lord. 20 And he closed the book, and he gave it again to the minister, and sat down. And the eyes of all them that were in the synagogue were fastened on him. 21 And he began to say unto them, This day is this scripture fulfilled in your ears.

Jesus is the Christ who healed people and preached the gospel of salvation according to the prophecies of the Old Testament. (Matthew 11:3-5, Luke 7:21-22, Acts 10:38)

Matthew 11:3 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.

Luke 7:21 And in that same hour he cured many of their infirmities and plagues, and of evil spirits; and unto many that were blind he gave sight. 22 Then Jesus answering said unto them, Go your way, and tell John what things ye have seen and heard; how that the blind see, the lame walk, the lepers are cleansed, the deaf hear, the dead are raised, to the poor the gospel is preached.

Acts 10:38 How God anointed Jesus of Nazareth with the Holy Ghost and with power: who went about doing good, and healing all that were oppressed of the devil; for God was with him.
