Heb 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 comes to the earth again for our salvation. God comes to the earth with the flesh like Jesus came with the flesh.
And then, how can we find out him?
God comes to the earth for bringing us salvation. We must know how God gives us the salvation.

John 6:53-54 "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."

Jesus gave the eternal life to those who believed him as God through his blood.

Mt 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."

We can understand that the wine of the Passover represents the blood of Jesus.
It means that God gives us the salvation through the Passover.
It also means that the one who establishes the Passover, the new covenant, is our Almighty God.

The Bible testifies that. In the Bible, it is written that God saves us in last days through the finest of wines.

Is 25:6-9 "On this mountain the Lord Almighty will prepare
a feast of rich food for all peoples,
a banquet of aged wine—
the best of meats and the finest of wines.
On this mountain he will destroy
the shroud that enfolds all peoples,
the sheet that covers all nations;
he will swallow up death forever.
The Sovereign Lord will wipe away the tears
from all faces;
he will remove his people’s disgrace
from all the earth.
The Lord has spoken.
In that day they will say,
“Surely this is our God;
we trusted in him, and he saved us.
This is the Lord, we trusted in him;
let us rejoice and be glad in his salvation.” "

I hope all the people keep the Passover, meet God who came to the earth and established the Passover for our salvation and receive the salvation!!
