Confession of Faith
Chapter 8: Of Christ the Mediator
Although the work of redemption was not actually wrought by Christ till after his incarnation, yet the virtue, efficacy, and benefits thereof were communicated unto the elect, in all ages successively from the beginning of the world, in and by those promises, types, and sacrifices, wherein he was revealed, and signified to be the seed of the woman which should bruise the serpent’s head; and the Lamb slain from the beginning of the world; being yesterday and today the same, and forever.1
But when the fullness of time had come, God sent forth his Son, born of woman, born under the law, to redeem those who were under the law, so that we might receive adoption as sons.
I will put enmity between you and the woman,
and between your offspring and her offspring;
he shall bruise your head,
and you shall bruise his heel.”
and all who dwell on earth will worship it, everyone whose name has not been written before the foundation of the world in the book of life of the Lamb who was slain.
Jesus Christ is the same yesterday and today and forever. (ESV)
