What is God fundamental rule for good and bad?

Men have different notions of good and evil. God has only one. His is absolute and unchanging. Its called the righteousness of God.

Deu 32:4 He is the Rock, his work is perfect: for all his ways are judgment: a God of truth and without iniquity, just and right is he.

Psa 119:142 Thy righteousness is an everlasting righteousness, and thy law is the truth.

HE alone is the Judge of all human judges

2Ch 19:6 And he said to the judges, Take heed what ye do: for ye judge not for man, but for the LORD, who is with you in the judgment.

The Holy Bible instructs all in Gods righteousness so that he can save us.

2Ti 3:16 ¶ All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:

2Ti 3:17 >>>That the man of God may be perfect, throughly furnished unto all good works<<<

There is no better than "perfect."

There's no substitute for faithful Baptism, along with a lifetime of prayer and study, combined with full, faithful and regular participation in all the work, worship sacraments and devotions of the Holy Catholic Church. Once you're a member of the Church and the "Family of God" you have free access to all you need to have your sins forgiven, to please God and to store up all the recommended, heavenly treasures. Absent all of that, you're pretty much left to your own devices - which may or may not be effective, for the purpose of your eternal salvation.

you are missing the beginning, Revelation 12,7-17 . " 7 And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels," which sent us here in these flesh bodies to be tested, will we choose good or evil ? We are spirits, in this dimension, temporarily in flesh bodies, then we go back home....and soon it will finally be over.......

God has to have evil to justify his existence.

Funny how most of the evil perpetrated for eons of Humanity has been done in the name of Gods.

Christianity is one of the most used reasons for mass murders in history.

The catholic church was systematically involved in the holocaust through its support of Hitler and actually maintained an anti-semetic posture until the 1970s.

Read the Bible. There are 613 Commandments that GOD gave to Moses, and Jesus tells us we are required to Keep Obeying ALL of them.  Plus the new Commandments Jesus taught us from GOD.

We also have to Not hate others. Even if one is a church leader, yet dies hating even one other person, they will go to Hell. 

Heaven is a place that is ALL LOVE! 

god wants only those who are righteous and those who are willing to repent and turn around from their

bad ways,

no once saved always saved in gods law

Jude 5, RS: “I desire to remind you, though you were once for all fully informed, that he who saved a people out of the land of Egypt, afterward destroyed those who did not believe.”

Matt. 24:13, RS: “He who endures to the end will be saved.”

(So a person’s final salvation is not determined at the moment that he begins to put faith in Jesus.)

Phil. 2:12, RS: “As you have always obeyed, so now, not only as in my presence but much more in my absence, work out your own salvation with fear and trembling.”

(This was addressed to “the saints,” or holy ones, at Philippi, as stated in Philippians 1:1. Paul urged them not to be overly confident but to realize that their final salvation was not yet assured.)

Heb. 10:26, 27, RS: “If we sin deliberately after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, but a fearful prospect of judgment, and a fury of fire which will consume the adversaries.”

(Thus the Bible does not go along with the idea that no matter what sins a person may commit after he is “saved” he will not lose his salvation. It encourages faithfulness.

Hebrews 6:4 For as regards those who were once enlightened and who have tasted the heavenly free gift and who have become partakers of holy spirit 5 and who have tasted the fine word of God and powers of the coming system of things, 6 but have fallen away, it is impossible to revive them again to repentance, because they nail the Son of God to the stake again for themselves and expose him to public shame.

, where it is shown that even a person anointed with holy spirit can lose his hope of salvation.)

The rule is this, God so loved the world that he sent his only begotten son, so that whoever believes in him, and does good, will have eternal life in paradise.

Before God there is no distinction of race, whoever does his will will will be welcomed by his love, and as a reward, will have eternal life in joy, and in the peace of his soul!

Not so for sinners, whoever makes sin, and does not convert from his wicked way, his condemnation will be eternal hell, where you suffer moderately, and you will cry for all eternity.

There will be no possibility of going back!

There is no rule.

Here we are, just us. Want to get along or fight?

We make rules, we write books, we take drugs and see strange things and write about them. We start religions and it is our devotions to our own structures of thought that divide us. We antagonise, we "strongly believe", we throw bricks at each other, and it is us warning us of the consequences of not believing in our own machinations.

If there is more beyond our imaginings, of it we know not. We are the ones egotistical enough to think we are correct.

There is none as there are no gods.
