These excerpts on the divine balance of pain and pleasure are taken from Dallas Willard's "The Allure of Gentleness: Defending the faith in the manner of Jesus."
The parenthetical notes are added by me for clarity.
God's purpose within human history, is to create for Himself a living abode - a community of free, conscious, living beings. (To accomplish His high purpose both pleasure and pain are necessary.) Pleasure and pain are, in a word, the positive and negative poles between which flow the currents of human life. Detach one pole, and this life will cease. People who ask for a painless world do not truly know what they are asking for.
It is only in the heat of pain and suffering, both mental and physical, that real human character is forged. One does not develop courage without facing danger. One does not develop patience without trials. One does not develop wisdom without heart and brain-racking puzzles. One does not develop endurance without suffering or temperance and honesty without temptations.
These are the very things we treasure most about people. Ask yourself if you would be willing to be devoid of all these virtues: Courage, patience, wisdom, endurance and honesty. If your answer is no, then don't scorn the means of obtaining them. The gold of human character is dug from torturous mines.
I'm not saying that we should go looking for pain, so that we can develop character. This is not at all necessary. All we need to do is make an honest and thorough effort to discover what is right and wrong, good and bad, and, when we are convinced on these points, then simply go out and face life for what it is worth. There will be plenty of opportunity to develop character. But you will never develop character by running from unpleasant situations, any more than you will develop your intellectual capacities by running away from study or tone up your six-pack abs by avoiding exercise.
God allows people to suffer precisely because He is benevolent. It's for our best. I assume that God wishes to be able to write some epithet over the episode of human history other than, "And a good time was had by all." (Is God only good) if He is a Jolly Good Fellow, running to satisfy our every whim and fancy and ease our every pain? Dallas Willard
On a personal note, when I think of the parents I most respect, they are the ones who do not give in to every whimper and whim of their children. They know and understand that both the rod of correction coupled with the staff of comfort and protection, provide the guardrail parameters needed to develop the character of Christ. Indeed, "The gold of human character is dug from torturous mines." And that gold is the coin of the Kingdom in the purchase of GOD's Good Life.
