Jesus Has Completed the Work

“If the Lord Jesus Christ had not literally risen physically from the grave, we could never be certain that He had ever really finished the work. If He has died for our sins, we must not only be certain that He has died, but that He has finished dying, and that there is no longer death. When God raised His Son from the dead, He was proclaiming to the whole world, 'I am satisfied in Him: I am satisfied in the work He has done. He has done everything. He has fulfilled every demand. Here He is risen—therefore I am satisfied with Him.'

Not only that. The Resurrection proved that He has conquered every enemy that was opposed to Him, to God, and to us. He has not only satisfied the law and conquered death and the grave, He has vanquished the devil and all his forces, and hell and all the principalities and powers of evil. He has triumphed over them all, and He proves it in the Resurrection. The devil cannot hold Him; death and hell cannot hold Him. He has mastered them all; He has emerged on the other side. He is the Son of God, and He has completed the work which the Father had sent Him to do.”
