Where is the Paradise or the Heavenly Kingdom?

[ Revelation 21:4 ] ‘He will wipe every tear from their eyes. There will be no more death’[a] or mourning or crying or pain, for the old order of things has passed away.”

The Paradise is where there will no more death or mourning or crying or pain.
We must try to do our best to return to the Heavenly Kingdom where there is filled with eternal happiness.

First, we need to know where we came from and where we are going after death.
The Bible teaches us that all people on this earth were angels in heaven but were expelled to the earth due to sins which could not be forgivable.
Since we came to the earth due to sins, we must be forgiven to return to heaven.

For the forgiveness of sins, Jesus established the Passover of the new covenant.

[ Matthew 26:28 ] This is my blood of the[a] covenant, which is poured out for many for the forgiveness of sins.

However, the new covenant disappeared during the Dark Ages. According to the prophecy of the Bible, Christ Ahnsahnghong broguth it back to us to re-open to the way to the Heavenly Kingdom.

We must keep the Passover of the new covenant and believe in Christ Ahnsahnghong who came as the Second Coming Jesus according to the prophecies of the Bible.
