Just as the moral law of God applied to the angels in heaven, the moral law of God applies to humans on Earth. This moral law of God is called the Ten Commandments of God. god gave these commandments through Moses some 3,400 years ago and they still apply today.
To break a Commandment of God is to sin against God, and the penalty for sin is firstly separation from God and then at the appointed time of God to be cast into the eternal Lake of Fire, which is the Second Death. As the Bible tells us.
12 I saw the dead, the great and the small, standing before the throne, and they opened books. Another book was opened, which is the Book of Life. The dead were judged out of the things which were written in the books, according to their works (sins).
13 The sea gave up the dead who were in it. Death and Hades gave up the dead who were in them. They were judged, each one according to his works (sins).
14 Death and Hades were thrown into the Lake of Fire. This is the Second Death, the Lake of Fire. 15 If anyone's name was not found written in the Book of Life, they were cast into the Lake of Fire. Revelation 20:12-15.
God created the Lake of Fire to burn up the rubbish – Satan and his angels who followed him in rebellion against God. Sadly, it was also created for humans who like those angels live their lives in rebellion against God and the laws of God. This may seem harsh to some people, but when we are in heaven we will thank God for not letting anyone or anything spoil heaven.
Jesus described heaven as paradise (Luke 23:42-43).
In heaven there won't be any graves, hospitals, prisons, ruling elite or poverty-stricken, second-class citizens. No armies, no wars, no sickness disease or death, no oppression, no prejudice, no one living in substandard subhuman conditions.
In heaven there isn’t any slavery, nor malice or thoughts of murder to one another. There isn’t any greed or wanting to have more or wanting to be better than anyone else.
In heaven the angels don’t hate God or make jokes about God, for they love God. Angels don’t lie, steal or cheat. They are reverent to God, they don’t want to offend God with anything they think, say or do.
Their purpose is to love God, and to love to serve God with all their heart, soul, mind and strength, and to love one another as themselves. It is the laws of God and the joyful and respectful obedience of the angels, that make heaven what it is – Paradise.
