For we know that since Christ was raised from the dead, he cannot die again; death no longer has mastery over him.
And in the NKJV --
knowing that Christ, having been raised from the dead, dies no more. Death no longer has dominion over Him.
Ahn Sahng-Hong died in 1985. The Bible tells us that Jesus Christ will not die again. Therefore, Ahn Sahng-Hong cannot be Christ.
I was recently asked by a WMSCOG member if I thought death had power over Jesus to begin with.
Now that's a good question, but when asked in this way by the WMSCOG it can be a tricky question. If you answer yes, they can return with, "So you don't believe Jesus was all powerful?" If you answer no, they can return with, "Death did not have power over Him yet He willingly came and died. It is the same with Ahn Sahng-Hong."
The question needs to be more specific for a proper answer.
For the question, did Jesus have the power to avoid dying on the cross? Yes, He did.
Matthew 26:53 says "Or do you think that I cannot now pray to My Father, and He will provide Me with more than twelve legions of angels?"
For the question, did Jesus have an invincible human body? No. His body died on the cross.
Philippians 2:7-8 says "but made Himself of no reputation, taking the form of a bondservant, and coming in the likeness of men. And being found in appearance as a man, He humbled Himself and became obedient to the point of death, even the death of the cross."
Jesus willingly came in a human body so He could satisfy our debt for our sins. In order for that sacrifice to take place, He had to allow death to have power over that body. If it had not been a perishable, human body, how could it have been a substitute for us?
But death could not maintain power over Him. He rose from the dead with a glorified, imperishable body.
1 Corinthians 15:42-43 "So will it be with the resurrection of the dead. The body that is sown is perishable, it is raised imperishable; it is sown in dishonor, it is raised in glory; it is sown in weakness, it is raised in power"
Death cannot have any power over an imperishable body.
1 Corinthians 15:54 "When the perishable has been clothed with the imperishable, and the mortal with immortality, then the saying that is written will come true: “Death has been swallowed up in victory.”"
Jesus ascended to heaven with that imperishable body (Acts 1:9-11) and there is no reason to think that His imperishable body has expired or is no longer available to Him.
"... This same Jesus, who was taken up from you into heaven, will so come in like manner as you saw Him go into heaven."
The difference here is that the World Mission Society Church of God teaches that Jesus needed a new human body to be born into (which would then have to die again), while mainstream Christianity teaches that Jesus doesn't need to be born into a new human body because He still has His imperishable, resurrection body, which will never need to die again.
