What is the point of existing?
That’s an excellent question, and probably a question anyone who has ever existed will ask themselves at some point. As members of The Church of Jesus Christ of Latter-day Saints we proclaim that we are the eternal offspring of divinity, our Heavenly Father and Mother. We are their sons and daughters. The point of our existence, both pre-mortal and mortal, is to reach the full measure of our creation — eternal lives. The full measure of our creation is to become like our Heavenly Father. In order to accomplish this our earth experience was absolutely necessary:
1) To become like our heavenly parents we needed to obtain a body, a physical body of flesh and blood.
2) To become like our heavenly parents we needed opportunities to learn, to know good from evil.
3) To become like our heavenly parents we needed to be tested, and that testing is a result of being enticed by good vs evil in order to bring about righteousness.
4) Part of becoming like our heavenly parents is the opportunity to experience joy. Adam fell that men/women may be, and men/women are that they might have joy.
None of these points are in any specific order of hierarchy, and I am not sure trying to would serve any good purpose. Without a body we can’t become like our Heavenly Father and Mother. Without being tested we would not grow, and we would not increase in knowledge. Without opposition we wouldn’t know opposites, and if we did not know opposites we would never be able to experience joy. In essence, we must know the bitter in order to value the sweet.
