We cannot know the mystery of God correctly with common sense and wisdom of the world.
So, how can we know it correctly?
The Bible tells us that only people who have received the forgiveness of sins through the blood of Jesus will receive wisdom and understanding from God so that they can know the mystery of God correctly.

Ephesians 1:7~9
In Him we have redemption through His blood, the forgiveness of sins, in accordance with the riches of God's grace. that He lavished on us with all wisdom and understanding. And he made known to us the mystery of His will according to His good pleasure, which He purposed in Christ.

If so, how can we receive the forgiveness of sins through the blood of Jesus?

Matthew 26:19,26~28
So disciples did as Jesus had directed them and prepared the Passover.
..Jesus took bread, gave thanks...."Take and eat; this is my body." Then he took the cup, gave thanks..."Drink from it, all of you. This is my blood of the covenant, which is poured out for many for the forgiveness of sins..."

We can receive the forgiveness of sins by keeping the New Covenant Passover.
Then, what is the mystery of God that we can know through the wisdom and understanding that God has given us by keeping the New Covenant Passover?

Colossians 1:26~27
The mystery that has been kept hidden for ages and generations, but is now disclosed to the saints. To them God has chosen to make known among the Gentiles the glorious riches of this mystery, which is Christ in you, the hope of glory.

We, who have received the forgiveness of sins by keeping the Passover, which was granted by Jesus's sacrifice, can recognize the Christ who has been hidden for ages and generations.
If so, who is the Christ whom we must meet and receive in the age of the Holy Spirit?

Revelation 22:17
The Spirit and the Bride say, "Come!" And let him who hears say, "Come!" Whoever is thirsty, let him come; and whoever wishes, let him take the free gift of the water of life.

The Spirit refers to God the Father, Christ Ahnsahnghong and the Bride refers to God the Mother who has been kept as the mystery of God for ages and generations.
I hope that you will receive abundant wisdom and understanding from God by keeping the New Covenant Passover and be saved by God the Father and God the Mother.
