The reason why the Wolrld Misson Society Church of God [wmscog] calls Ahnsahnghong-nim“Christ“ , is that He fulfilled all the prophecies about the Second Coming Christ in the bible.
The Bible prophesied about the place where the Savior would come. At the time of Jesus’ first coming, it had been prophesied that Jesus would come from Bethlehem. Like this, the Bible prophesies the “Place” where the Second Coming Christ will appear and start his salvation work [Heb 9:28] . The place is “Korea”. Let us check about the salvation of the Second Coming Christ which starts “from the east(Korea) ″ through the prophecy of “Seal Of God” in the book of Revelation.
The Salvation of the Second Coming Christ which starts from the East
< “Seal of god” coming up from the “east” >
Rev 7:1-3 NIV [After this I saw four angels standing at the four corners of the earth, holding back the four winds of the earth to prevent any wind from blowing on the land or on the sea or on any tree. Then I saw another angel coming up from the East, having the seal of the living God. He called out in a loud voice to the four angels who had been given power to harm the land and the sea: “Do not harm the land or the sea or the trees until we put a seal on the foreheads of the servants of our God.”]
What do the ” Four Winds”of the earth mean? Since it is written that there will be disasters to harm the land or the sea when the winds blow, the wind represents “Disasters”; as the four winds are blown to the whole world, from all directions, it means the Last Disaster that will destroy the world.
The work of God’s putting a seal before the disasters fall upon the world is the last work of salvation that God carries out to save His people.
Where does the work of salvation start from? It starts from the east. Then, where does Jesus come from at the time of His second coming? He comes from the east.
Then, what does the “Seal of God” mean? It is the Passover of the New Covenant because there is no other law of God but the Passover, in which God promises to save His people from disasters.
We can guess its pupose from the word ‘Passover’. Originally, a word, ‘Passover’ came from each word ‘pass’ and ‘over’. What passes over us? Disasters.
As we know, the last work of salvation is to be carried by the Second Coming Christ because the purpose of the Second Coming Christ is to bring God people salvation at the last days. [Heb 9:28]
Which means, the Second Coming Christ is sure to appear in the east and preach the Passover of the New Covenant from the east.
Only one in the world who restored and preached the Passover of the New Covenant Christ Ahnsahnghong and He was born in Korea in the east from the Patmos Island where apostle John saw the revealtion. This is the one of the reasons Christ Ahnsahnghong is the Second Coming Christ .

WMSCOG Where Christ Ahnsahnghong & God The Mother Dwell 
the seal of God must be opened by the Root of David,Second coming Jesus, Christ ahnsahnghong who brought the Passover
2000 years ago Bethlehem is holy land because Jesus was born. But now Korea is New holy land because Chirst Ahnsahnghong was born
As the bible testifies, Christ Ahnsahnghong appeared a second time in the flesh like the time of his first coming to bring us salvation, the New Covenant Passover.[Heb 9:28]
Thru the prophecies of the bible we can recognize true savior giving us salvation, that’s the reason God gave us the prophecies of the bible.
Jn 13:19 [“I am telling you now before it happens, so that when it does happen you will believe that I am He. ]
Christ Ahnsahnghong is “HE”, savior of this age who we have been waiting for.
Why we have to know is in Rev Ch 7:1 is that it is about the last age before the heaven. So it is very important for the salvation. Nevertheless, many Christians don’t know and be interested
We should believe in the Savior who brought us the Seal of God or the Passover through which we can be protected from disasters. Christ Ahnsahnghong restored the Passover and opened the way to the kingdom of heaven again according to the prophecies of the Bible.
