There are many churches in the world with many different denominations and different doctrines.
No matter how many churches claim to believe in God, it is meaningless if God does not acknowledge it.
So, are all these churches recognized by God as His people? Sadly, that is not the case.
God has recorded in the Bible the exact standards by which he distinguishes between those who are God's people and those who are not. And because God said that only those who do God's will will go to heaven, not those who say they believe in God,
This means that only those who know God's will and act according to it can become God's people, and only such a church becomes a church recognized by God.

Matthew 7:20–21
“Thus, by their fruit you will recognize them.
Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven,
but only the one who does the will of my Father who is in heaven.”

The core truth that God Himself established and commanded to keep until the end to distinguish His people is the New Covenant Passover.
The New Covenant Passover is the eternal covenant established through the blood of God's sacrifice, and it is the truth of life that promises us the forgiveness of sins and the blessings of eternal life.
The Passover is a precious feast that contains the principle of inheriting the flesh and blood of God and becoming one with God. Those who do not celebrate the Passover have no relationship with God and naturally cannot become God's people.
Because it is such an important truth, the New Covenant Passover was established by Jesus 2,000 years ago as his final will to provide salvation to mankind.
After the New Covenant Passover was abolished through the Council of Nicaea in AD 325, no people of God or churches recognized by God could be found in this world, and the path to salvation was completely blocked.
God, who took pity on us, came a second time according to the prophecy of the Bible, restored the lost New Covenant Passover, and gathered God's people again. He is Christ Ahnsahnghong and God the Mother.
The Church of God is the only church that keeps the New Covenant Passover, and those who keep the New Covenant Passover in the Church of God are recognized as God's people and receive the eternal blessings of heaven.
