On September 12, 2015, I gave a presentation (called "Love Unleashes Life") at Calgary's 40 Days for Life formation afternoon. In that presentation, I quoted from St. John Paul II's "Salvifici Doloris" (On the Christian Meaning of Human Suffering). He wrote,
"We could say that suffering . . . is present in order to unleash love in the human person, that unselfish gift of one’s 'I' on behalf of other people, especially those who suffer. The world of human suffering unceasingly calls for, so to speak, another world: the world of human love; and in a certain sense man owes to suffering that unselfish love that stirs in his heart and actions."
The wonderful Victor Panlilio kindly recorded my presentation, and this (above) is a one and a half minute clip he put together.
