“By faith Abel offered unto God a more excellent sacrifice than Cain, by which he obtained witness that he was righteous, God testifying of his gifts: and by it he being dead yet speaketh.”
King James Version (KJV)
11:4 By faith - In the future Redeemer. Abel offered a more excellent sacrifice - The firstlings of his flock, implying both a confession of what his own sins deserved, and a desire of sharing in the great atonement. Than Cain - Whose offering testified no such faith, but a bare acknowledgment of God the Creator. By which faith he obtained both righteousness and a testimony of it: God testifying - Visibly that his gifts were accepted; probably by sending fire from heaven to consume his sacrifice, a token that justice seized on the sacrifice instead of the sinner who offered it. And by it - By this faith. Being dead, he yet speaketh - That a sinner is accepted only through faith in the great sacrifice.
Heb 11:4 Abel offered to God a more excellent sacrifice than Cain. See the account of Ge 4:1-5. Abel's faith was probably shown in offering just such a sacrifice as the Lord demanded, while Cain made an offering according to his own ideas. By which he obtained witness that he was righteous, God testifying of his gifts. In some way the Lord testified his approval of Abel's sacrifice, and showed his disapproval of Cain's, perhaps by sending fire to consume Abel's. And by it he being dead yet speaketh. By his faith. His faith speaks to all ages.
