The reason our culture accepts abortion so easily is that adults have ceased to live.
People are told that sex is life and when that doesn't satisfy there is nothing else to be done. Rather than having a kid who has a hard or even average life we say that abortion is better because it would be better for them never to be born. I think many people wish they had never been born. If we truly lived and were fully alive then we wouldn't look at even a hard life as something of no value.
Even Christians who fight abortion seem to have no answer to the suffering ache and grief of life. We stand useless, the screen door on the submarine, wondering at our own lives and failing to live. I know because I do the same more often than I would like. I forget to find the joy in the pain, the hope of God in the nauseating sorrow, and instead work to drown in all out with another book, TV show, or row of stitches. I am willing to seek numbness rather than face the sharp pain of joy. I am willing to trap myself in a small cocoon world and stay there instead of living life the way God has meant it to be, full of fire and glory.
To see the God of the Universe is like Isaiah said it was: There was incredible pain and shame and humility at seeing his own sin in the presence of God's holiness. There was joy at being spoken to by God. There was pain at the fire of the hot coal being pressed to his lips. Then joy at being cleansed and ordered by God. And then sorrow at the sins of the people. And finally joy at the coming of the Messiah.
One does not come without the other, they are inseparable. And when we choose to see only the pain, life itself feels unendurable. When we only listen to the sad part of the story and forget the parts of the story to come, we live without life. And in doing so, we abort our own lives, the gifts God has so graciously given us.
