In case anyone is wondering, this is what correct theology looks like (or at least, the best version of which I presently know):
God, the all-powerful being, creates humanity. By breathing a special breath of life into them, He distributes a portion of His power to them, with the goal that they would exercise that power wisely. That power is new to humanity, so humanity takes time to learn to use it properly. When they do well, it gives them joy. When they mess up, it is painful, even though often a specific individual’s sin causes immediate pain to another innocent individual. Pain makes them aware of imperfections to be improved upon, while joy helps them know when they’re improving in the right direction.
Once upon a time, humanity experienced neither joy nor pain. Hence they did not have a first-hand experience of what was Good (joy-inducing) or Evil (pain-inducing). Naturally, they did not know how bad it was to disobey God. One day, they decided to eat the forbidden fruit of the tree of knowledge of Good and Evil. Having done so, they gained the ability to feel comfort and pain, and hence gained a first-hand appreciation of Good and Evil. They soon discovered that being naked wasn’t so good. Also, that there is a difference between truth (wisdom that leads to joy) and lies (foolishness that leads to pain). With this newly acquired ability, humanity proceeds to its next phase of existence.
Humanity then goes on to experience countless cycles of partial success and failure, through which wisdom is accumulated and passed on through generations of human civilization, of which scripture is an integral part. It culminates in the historic event when God deemed it was the right time to reveal Himself intimately as a human being, Jesus. Humanity then makes perhaps the worst mistake ever: murdering God’s incarnation / representative, Jesus. God then raised Jesus from the dead, to prove to humanity that Jesus represented humanity in its perfect form. I.e. the cross-bearing Jesus was humanity in its true, intended form, the Human made in God’s image. Hence, humanity is supposed to learn from Jesus, and thus live up to its true, glorious purpose: to exercise divine power wisely over all of God’s creation.
Jesus’ cross-bearing has a profound moral significance: that each person should use his power to right the wrongs that exist in the world, even the wrongs that did not originate from himself. That everyone should forgive and reconcile with a poor person who has wronged you but is unable to adequately compensate for it, as long as he repents, even if you suffer undeserved losses as a result, etc. And Jesus exemplified his principles as he willingly bore the cross himself, having dedicated his life to teaching God’s truth, while being condemned to the cross by those who rejected his teachings. And He specifically instructed his disciples to do likewise: to bear the unjust suffering required to bring justice to the world. Unbelievers deemed Jesus’ teachings as foolishness. But the resurrection proved that Jesus teachings were true wisdom worth following.
In this way, Jesus’ death and resurrection can be thought of as necessary / ideal, because action speaks louder than words: in order to explain a new concept, concrete examples are needed for the true meaning to be properly conveyed. So Jesus used himself as the perfect example.
Since Jesus represents humanity’s final moral destination, individual humans who do not eventually become like Jesus, will lose the right to exercise divine power. I.e. the divine breath of life will be taken away from them permanently. Because to live as a human is to share a portion of God’s divine power, and exert influence upon the world.
Hence to those who follow Jesus, God is like the all-powerful Father who is responsible for His children’s upbringing. Naturally, when His children mess up, it is ultimately God’s responsibility to fix it. What Jesus has done is a large part of God’s way of exercising His divine power and responsibility to make things right.
And so God, together with Jesus and the rest of His adopted children, will work to bring about the perfect world populated by a perfected humanity. When humanity has developed their science and morality to the point of perfection, human beings would naturally have complete control over both nature and human society, so that physical evils (natural disasters) and spiritual evils (human sin) will no longer exist.
When we reach that state, the 6th day of creation is finally complete, and, as it is written in scripture, God sees all that he has made, and it is very good indeed.
