"And with great power gave the apostles witness of the resurrection of the Lord Jesus: and great grace was upon them all" (Acts 4:33).
There are multitudes today who believe that Christ's resurrection was a "spiritual" resurrection, insisting that the idea of a dead body returning to life after three days in the grave is completely unscientific and impossible.
This was not what the apostles preached with great grace and great power, however. They would hardly have been excited about any kind of spiritual resurrection, since everyone -- both Jews and the pagan Gentiles -- believed in life after death. If that was their message, no one would have doubted, and no one would have cared. Even when the disciples saw the resurrected Christ, they first "supposed that they had seen a spirit" (Luke 24:37). Christ even had to urge them to "handle me, and see; for a spirit hath not flesh and bones, as ye see me have" (Luke 24:39).
When the disciples finally became convinced of His bodily resurrection, they were quickly transformed into courageous evangelists, willing even to die in support of their glorious message of salvation. The resurrection was, indeed, contrary to scientific law and all human experience, and this very fact proved to them that their Lord was Himself the divine lawgiver and Author of all human experience. All other founders and leaders of human religions, ancient or modern, are themselves subject to death, but He alone has triumphed over death. Only the Creator of life can conquer death, and the resurrection proves that Jesus Christ is Creator, as well as Savior.
Therefore, when we today, like the apostles of old, proclaim the resurrection of Christ, we know that His name is above every name, and this enables us also to witness with great power, in great grace. HMM
