Majority of people of the book, do not acknowledge Jesus who prophetically warned.

4:159 Among the people of the book are few who would have acknowledged him before his death, and on the day of Resurrection he will be witness against them.

Note:

The majority of the people of the book, unfortunately, do not acknowledge Jesus who prophetically warned them against the teaching of Pharisees. They have accepted being the sheep of St. Paul, who never met Jesus, yet had intense arguments with Peter (Cephas) and Barnabas (Acts 15:36-41 ; Galatians 2:11-14 ; 4:10), and who was also not trusted by disciples who escaped from him (Acts 9:26 ). The disciples knew that he was a wolf in the midst of sheep. They knew that he was a Pharisee (Acts 23:6 ), and they also knew well the repeated warning of the Messiah (Matthew 16:11-12 ; 23: 13-33; Luke 12:1-2 ). It was the self-appointed disciple Saul (The Acts 26:16-19 ) who after changing his name to Paul (Acts 8:3 ; 22:3), changed the name of the supporters of Jesus too (Acts 24:5 ; Acts 11:26 ). It was Paul who provided grounds for the polytheistic Doctrine of the Trinity, created the story of Jesus' sacrifice for our redemption, raised Jesus to his "Father's right side" for judgment, nailed the written code to the cross (Colossians 2:14 ), thereby dismissing Jesus (Matthew 19:16-19 ). He perverted the main message of Jesus, which was to worship God alone. He cunningly cursed him (Galatians 3:13 and Deuteronomy 21:23 ), and he became "all things to all men in order to win them" (1. Corinthians 9:20-22 ). Indeed, it is not Jesus, the son of Mary, but it is this dubious character that the majority of Christians are now following(edip).
