John Piper on Abortion

"The helpless are crushed, sink down,
and fall by his might.
He says in his heart, 'God has forgotten,
he has hidden his face, he will never see it.'

Arise, O LORD; O God, lift up your hand;
forget not the afflicted.
Why does the wicked renounce God
and say in his heart, 'You will not call to account'?
But you do see, for you note mischief and vexation,
that you may take it into your hands;
to you the helpless commits himself;
you have been the helper of the fatherless.
Break the arm of the wicked and evildoer;
call his wickedness to account till you find none." (Psalm 10:10-15)
