We’re heard that the kingdom of heaven is near at hand and it means we should prepare for the kingdom of heaven.
As the Bible says, gold or silver or precious stones or any tangible asset, we can take none of them.

When Alexander the Great died, the first king of Greece who established the Greek Empire,
he left his will breathing his last breath,
“Let both my hands be kept dangling out of my coffin so that many who gathered there realize
that mankind came empty handed into this world and go empty handed, too.”
Unfortunately he didn’t prepare for the heaven until he was about to return.
He tried to take his wealth and treasure but he failed.

Jesus also mentioned 2,000 years ago the same, the kingdom of heaven is near
when He was preaching the gospel.

Mt 4:17 From that time on Jesus began to preach, “Repent, for the kingdom of heaven is near.”

He emphasized that we should repent in order to go back to the heaven.
Then, how should we repent? It is defined in the dictionary that the word ‘repent’ is to contrite for past action
so that you can change your life for the better and you need to say that you are sorry for something wrong you have done.

Then what is the way to repent to be saved?
First of all we have to acknowledge that we’re sinner in heaven and committed grave sin against God Elohim.
And we have to do something good to be forgiven our forgiveness of sin.
It is to keep the Passover which is the only way to be forgiven our sin.

Mt 26:17~27 The disciples came to Jesus and asked, "Where do you want us to make preparations for you to eat the Passover?"
Then he[Jesus] took the cup, gave thanks and offered 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 find another good teaching as below:

Gal 5:22~25 The fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control.
Against such things there is no law.
Those who belong to Christ Jesus have crucified the sinful nature with its passions and desires.
Since we live by the Spirit, let us keep in step with the Spirit.

As God taught us that the entire law is summed up in a single command as a new command:
"Love your neighbor as yourself" and He has loved us, we must love one another.
It is to carry out His command and fulfill His will.

What should we prepare for the kingdom of heaven?

We have to repent our sins to be forgiven by God Elohim by keeping the Passover
and change our life by living by the Spirit, throwing away the sinful nature
and developing love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control
to bear the fruit of the Spirit. God Elohim, Christ Ahnsahnghong and Jerusalem Heavenly Mother will be pleased
when They see our changed spiritual being.
