Numerous excellent articles related to abortion have been published in the last week. Some are indexed here. This post by John Piper is especially powerful. Two excerpts:

Lincoln: “You say A. is white, and B. is black. It is color, then; the lighter, having the right to enslave the darker? Take care. By this rule, you are to be slave to the first man you meet, with a fairer skin than your own.”

Piper: “There are no morally relevant differences between white and black or between child-in-the-womb and child-outside-the-womb that would give a right either to enslave or kill the other.”
