You may think that the reason is the Bible. That's right. As it was written in the Bible, Jesus walked the thorny path and crucified in the cross to forgive our sins. Nothing can be found that his life hadn't been written in the Old Testament. According to the prophecies of the Bible, He came to this earth and returned to heaven.
In John 5:39, it definitely proves that Jesus is our savior who allows us to have eternal life and is testified in the Bible.
Jesus, the Almighty God has to come again, because it is the part of the prophecies of the Bible.
In the World Mission Society Church of God, we Do believe in Christ Ahnsahnghong as the Second Coming Jesus. This is not the popular idea and personal opinion, but this is fact. Because the Bible proves that he is the Second Coming Jesus.
We all should study why Christ Ahnsahnghong is the Jesus, himself, if you do believe in the Bible.
