I see a new world with no sin, so therefore a paradise. Consider the theory that sin and evil create or should I say bring entropy into whatever system it (sin) is introduced. As long as the cancer of sin survives, the system will continue to drift further and further into disorder, pain, suffering, corruption, until finally, the system will cease to be able to live. So in this real applicable way we can see just how the wages of sin is death. This is what I feel about sin as it relates to the new heavens and new Earth, it WON'T BE THERE!
The current world is infected and dying and the only way to survive is to come out of it. The means by which we can be redeemed from the world is what I term as The Divine Gift.
Scripture teaches us not to love the world because the world and all that is in it is passing away. I see sin as a sickness and death is the mechanism used to fight off the infection. Our universe combats sin by inflicting death so that sin cannot persist endlessly. Ultimately, death is intended to kill off the sin infection and once it has accomplished that task, it too will be done away with.
For those who survive this world, we will ever be mindful of two things. One being the Divine Gift that redeemed us from the curse of sin and secondly, the reprocussions of sin. With these things etched in mind, the survivors will not participate in or give sin a chance to be reborn in the new habitation because they know the consequences.
