Regarding the instance that He cannot die again- Christ Ahnshanghong and God the Mother.

Those who deny the Second Coming Christ, Ahnsahnghong, of the World Mission Society Church of God claim as follows:

The Bible says that “Christ cannot die again.” But Ahnsahnghong passed away. Therefore, He is not the Second Coming Christ.

However, they insist such a claim because they could not understand the matter of a spiritual body and a natural boy properly and interpreted the Bible wrongly.

If we have been united with him like this in his death, we will certainly also be united with him in his resurrection…. Now if we died with Christ, we believe that we will also live with him. For we know that since Christ was raised from the dead, he cannot die again; death no longer has mastery over him. (Romans 6:5-9)

This Verse means that those who are baptized will receive eternal life which does not die as Christ died and was raised from the dead. Of course, it does not mean that a natural body will live forever. They will live forever without death as God’s children with spiritual bodies.

…and they can no longer die; for they are like the angels. They are God's children, since they are children of the resurrection. (Luke 20:36)

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; it is sown a natural body [physical body], it is raised a spiritual body. If there is a natural body [physical body], there is also a spiritual body. (1 Corinthians 15:42-44)

The resurrection means that the natural body will be changed into a spiritual body to live for good. Just as a caterpillar is clothed with a new body of a dragonfly, so one who receives God will be changed to a new body which can live forever according to the promise of God.

I declare to you, brothers, that flesh and blood [what is made of flesh and blood] cannot inherit the kingdom of God, nor does the perishable inherit the imperishable. Listen, I tell you a mystery: We will not all sleep, but we will all be changed-- in a flash, in the twinkling of an eye, at the last trumpet. 

For the trumpet will sound, the dead will be raised imperishable, and we will be changed. For the perishable [what is mortal] must clothe itself with the imperishable [what is immortal], and the mortal with immortality. 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." (1 Corinthians 15:51-54)

Flesh and blood – visible bodies – cannot inherit the kingdom of God. It’s because we with bodies cannot enter the kingdom of heaven which is the kingdom of the Spiritual God. Therefore, the words “He cannot die again” are not about the natural body but the spiritual body.

Jesus, who had been in a spiritual body, has come a second time in the flesh as He did 2,000 years ago to bring salvation to mankind (Hebrews 9:28.) Those who truly understand and follow the will of God should at least know that the natural body is one thing and the spiritual body is totally another thing.
