Christ said the goal of humans should be eternal life (John 5:24). It is to be found in "the world to come" rather than this life (Mark 10:30).

To acquire eternal life, Christ said people need to overcome sin (Mat 25:46)(Luke 10:25-28) and believe in God or Christ (John 3:15, 10:28, 17:3). And people must reform (Luke 13:3-5).

Adding up these "commands" of Christ's means overcoming sin is the only relevant purpose in human life. There are responsiblities involved, like feeding the hungry (Mat 25:31-46). This means human life has a purpose and is used like a tool for salvation.

But human life is not an end in itself. People are not to store up earthly treasures but heavenly treasures (Mat 6:19,20). A person cannot serve God and mammon (Mat 6:24).

In other words, overcoming sin is the only thing Christ taught, and material life has no other purpose. The fact that material life ends after sin is overcome demonstrates that there is no other purpose but overcoming sin to material life. Christ's teaching to not seek indulgences in material life, while overcoming sin, demonstrates that there is not supposed to be any other purpose than overcoming sin to life.

The usual implication of fundamentalist preaching is that God tried to create a garden of Eden, but satan turned it into a world of sin. And they refer to an all-powerful and all-knowing God. They don't believe a word of their own preaching.

Sin existed before material life was created. In Genesis, satan was thoroughly corrupted by sin when he tempted Adam and Eve. The story is an allegory, but literalists try to read the origins of sin in it.

In human life there is a continuous gradient of degrees of corruption, from persons who are similar to satan to saints. It takes millions of years to get as corrupted as persons similar to satan. It didn't occur in the human society. Less corrupted persons didn't acquire their corruption in one life-time either. They brought their corruptions with them when they were born.

The most obvious reason to assume molecular life was created to overcome sin is because that is what it does and needs to do. It stabilizes objective realities, so persons can learn to relate to reality properly as the medium which defines life. Yet it is so problematic that it only has a temporary purpose.

God didn't change his mind when he decided the world is a corruption. He had temporary and limited purposes with the material world.

Since the entire concern of God and Christ is to overcome sin, there would not have been any other purpose with material life.

 

Atonement did not end sin. Offering blood is a paganistic corruption. The demon gods required murder as a test of loyalty, and then they would provide some protection or something. It's like the Mafia requiring extortion money. When Christ referred to offering his blood, it was not payment to anyone. It was self-sacrifice for advancing truth. The same is true of martyrs or military soldiers. The Christian martyrs were not paying Nero to please him. The soldiers at the Battle of the Bulge were not paying Hitler to please him. God is not a pervert like the demons who required murder as a test of loyalty. Christ had to be martyred to prove the truth about sin, because corrupters claim sin is so trivial that nothing needs to be done about it. So Christ showed that innocent persons and moralists are being destroyed because of the characteristics of sin. When society murders God for doing good deeds and teaching morality, then the nature of sin is demonstrated. It is a major problem that requires a major effort to overcome it. It says Paul was not fixed with a flash of light. If he were, no religion would be needed. The fraud of his theology and his disgraceful communication standards demonstrate that he was not fixed by a flash of light.
