If you have the chance, spend a few minutes at Al Mohler's blog and read the first three articles he has written this month on abortion. As usual for his writing, they are outstanding. After reading him on a regular basis, I am still amazed at his ability to cut to the heart of the matter, and these three articles are no different.
And, if you can stomach it, check out what John Piper had to say about the recent Supreme Court ruling concerning partial birth abortion. It is graphic, but some things need to be.
