Think of it this way:
I have suffered a miserable life...everyone has to some extent.
But God has given me so many wonderful experiences: Friends, family, nature, animals, sunsets, mountains, novels, movies...I could go on.
If I had been aborted, I never would have experienced the joy of the Lord. I never would have seen true life for what it is. It isn't the hurt, the constant struggle to make ends meet. It is loving encounters, beautiful skies, and following God to the best of your ability.
THAT is life, and I would go through TEN THOUSAND times more hurt to be able to experience a moment of it!
Do not promote denying children of their chance at life.
