The Jewish people offered animal sacrifices (through the priests) at the Temple, to ‘cover’ or put aside their sins. If the the majority of the Jews rejected Jesus, and the last Temple was destroyed in 70 AD, how have the Jews atoned for their sins since then?
Hebrews 9:22 says without the shedding of blood there is no forgiveness. In Old Testament times, animal sacrifices gave people who believed in a coming Messiah a temporary reprieve until the He came to provide a permanent remedy for their sins. At that time animal sacrifices became invalid for the duration of the Church Age (Hebrews 10:1-4).
Now, the only acceptable atonement for sin is the blood of Jesus. Speaking to the rulers and elders of Israel, Peter said, “Salvation is found in no one else, for there is no other name under heaven given to men by which we must be saved” (Acts 4:12).
Everyone who declines or neglects to accept His shed blood as payment in full for their sins, whether Jew or Gentile, will live and die in a state of unforgiveness.
Jesus said, “I am the way, the truth, and the life. No one comes to the Father except through me” (John 14:6).
