When the Lord Jesus was crucified, He said, “It is finished.” It proves that God’s work of saving mankind has been accomplished. Why are you saying God has carried out another work of judging, purifying and saving man?
“When Jesus came, He also did part of God’s work, and spoke some words—but what was the main work He accomplished? What He mainly accomplished was the work of crucifixion. He became the likeness of sinful flesh to complete the work of crucifixion and redeem all mankind, and it was for the sake of all mankind’s sin that He served as a sin offering. This is the main work He accomplished.”
