17 And He was handed the book of the prophet Isaiah. 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 has anointed Me to preach the gospel to the poor; He has sent Me to heal the brokenhearted, to proclaim liberty to the captives and recovery of sight to the blind, to set at liberty those who are oppressed; 19 To proclaim the acceptable year of the Lord.” 20 Then He closed the book, and gave it back to the attendant and sat down. And the eyes of all who were in the synagogue were fixed on Him. And He began to say to them, 21 “Today this Scripture is fulfilled in your hearing.” (Luke 4:17–21, NKJV)
Some Christians believe and are convincing others that Jesus preached the Law of Moses when He was on the earth. That is false doctrine. The fulfillment of Isaiah 61:1-2 in this passage could not be more clear. Jesus was sent to preach the gospel – the good news of redemption from sin’s captivity. That is why we must hear Him and not Moses, whose law could never give remission of sins (Matt. 17:5; Heb. 10:1-4). If Jesus did not preach the gospel when He came to earth, then He is not the Christ of prophecy. He did and He is.
