God's truths are the Passover, Sabbath ,and the seven feasts in three times. These truths are observed in Zion where God dwells. Therefore, Zion is the place of salvation. But, Satan destroyed Zion by abolishing all the truth. That's why God must come again, restore the truth, and rebuild Zion for us. Only when God comes to this earth and restore the truths, Zion can be rebuilt by God. Then, who did this work? He is Christ Ahnsahnghong. The Bible testifies that those who keep the rules of men such as Sunday worship will lose their wisdom and intelligence and become the spiritually blind, being unable to find Zion nor receive salvation. It is only the World Mission Society Church of God that recognizes Christ Ahnsahnghong and Heavenly Mother who have come to Zion as the Saviors and keeps the Seven Feasts in Three Times and the truth of the New Covenant holy.
