Today, there are so many churches and each of them has their own Bible interpretation and doctrine. And all of them claim that they have truth. It is said that there is only one gospel which God has allowed us.(Gal 1:6~10) Then, how can we distinguish between the church has truth and the church doesn't?
We can find the way to study about the Root of David. The Bible prophesied that only the Root of David can open the truth which was sealed.

Rev 5:1~5 "Then I saw in the right hand of him who sat on the throne a scroll with writing on both sides and sealed with seven seals. And I saw a mighty angel proclaiming in a loud voice, “Who is worthy to break the seals and open the scroll?” But no one in heaven or on earth or under the earth could open the scroll or even look inside it. I wept and wept because no one was found who was worthy to open the scroll or look inside. Then one of the elders said to me, “Do not weep! See, the Lion of the tribe of Judah, the Root of David, has triumphed. He is able to open the scroll and its seven seals.”"

No one can find the truth in the Bible except the Root of David. As only the Root of David can open the seal of truth, we should go to the church that to Rood of David has established.
Then, who is the Root of David?

Revelation 22:16 “I, Jesus, have sent my angel to give you this testimony for the churches. I am the Root and the Offspring of David, and the bright Morning Star.”

The Root of David is Jesus. At the first coming of Jesus 2,000 years ago, Jesus gave us the truth, that is the New Covenant Passover by which we can receive eternal life. Bur after Jesus's ascending and Apostle's death, it was abolished during the dark age. In other words, it was sealed. That's why second coming Jesus must come. Let's see the prophecy about it.

Heb 9:28 "So Christ was sacrificed once to take away the sins of many people.; and he will appear a second time, not to bear sin, but to bring salvation to those who are waiting for him"

As people wait for second coming Christ because there is no truth, Christ will come to the earth to bring salvation, that is eternal life. So Christ must appear in this last age a second time and bring the sealed truth, the New Covenant Passover. We can recognize the second coming Christ with the truth.

Today, there are numerous churches but there is only one Church that keep the New Covenant Passover. It is World Mission Society Church of God. New Covenant Passover has been given by Christ Ahnsahnghong. According to the prophecies of the Bible, Christ Ahnsahnghong is the Savior whom we has been waiting for. Therefore, let's believe in Christ Ahnsahnghong and keep the New Covenant Passover in World Mission Society Church of God.
