Christ is Isaac, the beloved Son of the Father who was offered as a sacrifice, but nevertheless did not succumb to the power of death. He is Jacob the watchful shepherd, who has such great care for the sheep which He guards.
“For since the law has but a shadow of the good things to come instead of the true form of these realities, it can never, by the same sacrifices that are continually offered every year, make perfect those who draw near.” – Hebrews 10:1
“When he said above, ‘You have neither desired nor taken pleasure in sacrifices and offerings and burnt offerings and sin offerings’ (these are offered according to the law), then he added, ‘Behold, I have come to do your will.’ He does away with the first in order to establish the second. And by that will we have been sanctified through the offering of the body of Jesus Christ once for all.” – Hebrews 10:8-10
