Why did God come to this earth in the form of flesh 2,000 years ago? It is to save sinners who have committed sins in heaven and are being chased out on this earth.

Matthew 9:13 But go and learn what this means: ‘I desire mercy, not sacrifice.’ For I have not come to call the righteous, but sinners.”

All human beings are destined to die because of the sins they committed in heaven. God said that the penalty for our sin is death.
However, through the sacrifice of Jesus who came to this earth, we can once again have the hope of going to heaven and the hope of eternal life.

Romans 6:23 For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.

Jesus came to this earth in the flesh and atoned for our sins.
To atone for our sins, He suffered on the cross, shed His blood, and offered Himself as a sacrifice. And He allowed the New Covenant Passover where we could receive redemption through the body and blood of God.

John 6:53-56 Jesus said to them, “Very truly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. Whoever eats my flesh and drinks my blood has eternal life, and I will raise them up at the last day. For my flesh is real food and my blood is real drink. Whoever eats my flesh and drinks my blood remains in me, and I in them.

Matthew 26:26-28 While they were eating, Jesus took bread, and when he had given thanks, he broke it and gave it to his disciples, saying, “Take and eat; “This is my body.” Then he took a cup, and when he had given thanks, he gave it to them, saying, “Drink from it, all of you. This is my blood of the covenant, which is poured out for many for the forgiveness of sins.

However, at the Council of Nicaea in 325 A.D., the New Covenant Passover established with God's sacrifice was abolished, and no one could be forgiven for their sins.
This is because no one can receive forgiveness of sins if they do not keep the Passover.
So God prophesied that He would come to this land once again.

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

God came to this earth a second time. The reason is for the forgiveness of our sins. Christ, who comes a second time, must restore the New Covenant Passover. If there is someone who restores the Passover of the New Covenant, it must be our God. The person who restored the Passover is Christ Ahnsahnghong. Therefore, WMSCOG believers believe in Christ Ahnsahnghong as the Second Coming Christ and as our savior.
