Martyn Lloyd-Jones writes:
The Resurrection is the great announcement of the momentous fact that Christ has finished the work He came to do. He is no longer "under the law." He is back in glory. Why? Because He has done everything that the Law could demand. Now the Law has exhausted itself upon Him, and He will die "no more."
He need not have died at all. Deliberately He came into the realm of sin and death, in order to deliver us from it all. Now He "dies no more. Death has no more dominion over Him!"
That is the meaning of the Resurrection. He has gone back into the realm above and beyond sin and law and death. He has conquered that entire realm, and He has returned to the glory from whence He came. That is the meaning of the Resurrection.
