When the Bible says that God cannot lie, it means that the laws He proclaimed are still in place. It's impossible for God to lie (unlike us). Why, because everything He said became an established truth. So if God said black is white, guess what? Black becomes white. God has such a pure nature of goodness and truth that He can't even look upon sin. He is aware of it but must turn away from it because of Who He is. His stand against sin is always the same: he abhors it and is moved to wrath against it. Romans 1:18  The result of disobedience in the Garden produced spiritual and physical death in our bodies. Our bodies were meant to live forever, but now that is impossible because of the sin we place upon them.

So what happened to us?! Were we tricked forever into losing our rights and privileges? Satan, who understood the unchangeable laws perfectly, was now in the ruler's seat of the world. Since everyone is born through a human being, we are born with a sin nature. It's our natural inclination. According to Law, we are guilty and doomed to death. Romans 5:12

Satan's fate will be Hell in the end, this he knows but his mission is clear - to take as many humans with him as possible. How will he be able to accomplish this? His tactics are to kill, steal and destroy, corrupt, devastate, hurt and harm.

Are we doomed
to eternal death?

Interesting Thought: How could God invoke a plan that would save His children and still stay within His Laws.
