When I think of my self, I try very hard to live as a right person.
However, whenever I go to church, pastor always tells me that I am a sinner and I need to repent. Then.... what is the sin that I have committed??

When we study about our soul, we come to understand that we have sinned in heaven, before the creation of the earth, before being born on this earth.
But we don't even remember the creation of the earth. How can we remember the sin that we committed in heaven?

We cannot remember exactly, but we can at least assume what we have done.

Romans 3:20 Therefore no one will be declared righteous in his sight by observing the law; rather, though the law we become conscious of sin.

What are the laws that God gave us? Let's find out through the Ten Commandments.

Exodus 20: 1-17
1) You shall have no other gods before me
2) You shall not make for yourself an idol ... you shall not bow down to them or worship them;
3) You shall not misuse the name of the Lord your God
4) Remember the Sabbath day by keeping it holy
5) Honor your father and your mother
6) You shall not murder
7) You shall not commit adultery
8) You shall not steal
9) You shall not give false testimony
10) You shall not covet your neighbor's house ...

As we can see, we have committed all these sins in heaven.
We worshiped other gods and we misused our Heavenly Parent's name. We murdered in heaven. We have stolen, we lied, we have sinned more and more...

Think about it. In this world, if someone misuses his parents name, what do we call him?
An immoral person. What if someone kills someone? Definitely he shall go to prison.

Through the Ten Commandments, we can see that we have truly sinned against God in Heaven and messed up the Heavenly orders and laws.
That's why we were expelled from heaven and now living a hard and trouble life in this world.

Then, how can our sins be forgiven? Can a sinner forgive another sinner? No.
Romans 6:23 For the wages of sin is death,

We each have our own personal sins and only through our death, our sin is payed.
That's why God (who has no sin and the one who has authority to forgive our sins) came to this world to take away my sin instead.

How can we have our sins forgiven?
Ephesians 1:7 In him we have redemption through his blood, the forgiveness of sins,
Only through Jesus precious blood we can receive the forgiveness of sins.
How can we receive Jesus blood?

Matthew 26:26 ... Jesus... took the cup (the vine) 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.

This is the day when Jesus gathered his disciples and kept the Passover.
Only through keeping the New Covenant Passover, our sins can be forgiven because we have received Jesus precious blood.

The Passover is the Heavenly Law to forgive all of our sins from heaven.
What happens when we do not keep the Passover?

Revelation 20:11-15 ... The dead were judged according to what they had done as recorded in the books... each person was judged according to what he had done... The lake of fire is the second death...

God gave each one of us the same time to repent for our sins.
Those who repent will surely go back to the kingdom of heaven, however, if we don't...
Then we will be judged from God according to what we have done from heaven and this earth.

What's your decision? How wise will you use your time?!
