The Bible records that God came to this earth a second time to set mankind free from the law of sin and death through the law of the Holy Spirit.
Following all the prophecies of the Bible, Christ Ahnsahnghong came to this earth in human form and restored the truth of the new covenant that had been lost by Satan, thereby guiding the children of God to the path of heaven.
Through the truth of the new covenant, we, who were sinners in heaven, were allowed to receive great blessings to be restored to our glory in heaven and to avoid punishment in hell.

Jeremiah 31:31–33
“‘The time is coming,’ declares the LORD, ‘when I will make a new covenant with the house of Israel and with the house of Judah . . . This is the covenant I will make with the house of Israel after that time,’ declares the LORD. I will put my law in their minds and write it on their hearts. I will be their God, and they will be my people.’ ”

As the Bible says, we become one through the new covenant, that is, the flesh and blood of Jesus, and it tells us that only those who have the flesh and blood of Jesus can be saved.
That is why the members of the Church of God keep the law of the New Covenant restored by Christ Ahnsahnghong who is the Second Coming Jesus, keeping it in mind.
