Again, Steve Hays does a good job illustrating vicarious atonement. He also relates substitution to the principle of asymmetrical agency:
Romans chapter 5 notes the similarities and contrasts regarding aspects of Headship. “Headship” is the theological concept of how humans are both condemned in Adam and justified in Christ. I once had the whole of Romans 5 memorized but now can only recite the first 8 verses. I am working slowly to regain the whole again or at least through verse 11 since its a good exhortation for daily life.
Romans 5 presents the big picture in Paul’s theological treatise to the Christians at Rome. I’ve written before about the Split Headship view which is self evident by merely reading this chapter. Humans have a natural connection to Adam but are represented by Christ in His substitutionary death for us. I want to touch on a connected topic of Headship found in Romans 5: Adam the “type.”
The second and last Adam (Jesus) is, of course, the antitype or fulfillment of the purpose of human creation. Heb. 2.7 tells us that humans were only temporarily created to be lower than the angels. So, how will humans to achieve this higher status? The answer is eternal union with Christ through redemption. Christ’s death was planned before the foundation of the world at probably the first day when, in a metaphorical sense, light was separated from darkness (but possibly before). It seems because the non-elect angels’ positions were forfeited, Christ is now filling those positions with replacements intimately connected with Him. Therefore, job openings are available, so run the race with endurance to claim the prize.
