As a Christian I believe that the notion of suffering as something necessary to grow up spiritually is a big lie.
The point is, suffering is inevitable. We grow up spiritually despite that suffering. Christ suffered for even those who denounced him. If you don't at least suffer sympathetically or empathetically for others in this current world then you've missed his message.
We must eliminate suffering.
That's not within our capability. Hence the need for Christ. We might seek to alleviate suffering to various degrees but we cannot eliminate suffering without God. This would include of course mental and well as physical suffering.
So...if we lived in a just world without greedy and money-hungry, bossy tyrants...well...that is a world where to raise your children.
If you read your scriptures I'm not sure we'll have children in the traditional sense after Christs return.
We have children and raise them in this world because that is the current essence of being human. Scripture says we shall be tested as in a fire. That includes the process of having children in an imperfect world. Not once does scripture advocate for not having children. Quite the contrary, in several places it emphasizes the importance of having a family regardless of the ills of the world.
But since we don't live in that world...it's better not to have kids. Let's fix the world, first.
God mad humans to procreate and thrive. That humans have mucked up the environment to do that in does not eliminate the basic human drives we were originally created with. IF we would be perfect we could all adapt to the current situations we find ourselves in without struggling to make the most appropriate choices. But we are not perfected yet are we. We are in the process. Thus for many humans the drive to have children is persistent and pervasive despite the conditions not being ideal. Of note though is the fact that our birthrates are collectively starting to decline worldwide but this is less due to a sudden collective increase in wise choices but more of a symptom of an unhealthy world.
Because you
seem to find it not much of a struggle to choose not to have children does not mean others shouldn't struggle with the option as well.
The problem is not me. It's the enslavers. The bossy people.
Your choice to not have children is not a problem - unless you wish to but can't or your mate wishes to but you don't. Then it may be a problem for you or your mate but that does not define you as the problem.
Technically, even in an idealized world the mere act of having children enslaves you to your children's needs. Such enslavement is not necessarily a bad thing. There can be corollary benefits despite the costs. Having a family itself causes spiritual growth when its healthy.
Humanity was created as a gregarious species. That gregariousness is best routed through family. Not having a family may simply make an unhealthy environment for the individual more unhealthy.
For example... I didn't create a human being that will be victimized by the devilish anarcho-capitalistic system. That's wonderful.
That makes me feel good and a better person.
If that makes you feel good and consequentially a better person by being capable of treating others better then I'm glad for you.
Not everyone births a child with the firm conviction that it will be victimized by the "devilish anarcho-capitalistic" system your speaking of though. Many parents have children in the hopes that that child will grow to help make the future a better place for themselves or others not a worse one.
Saying its wonderful is misplaced zealousness I think. What would be wonderful is not having your immediate environment dictate whether or not you can do what your healthy procreative drive compels you to do.
Well...I believe in a spiritual world, which is reachable after we die. There are not slaves or masters in that world.
We can only hope.
In the mean time we are stuck with what we a stuck with. In an ideal environment do you think you would like to have children? If so I cannot help but think that it is a struggle for you currently. If you do not care whether you have children or not - if you lack that drive - then you don't make the best spokesperson for not having children in this world since you wouldn't truly be capable of empathizing with those who do.
Gods blessings be upon you.
