It is a question that Mary Elizabeth Williams asked and wrote an article on back in 2013. Is it a question that resonates with you or do you find the idea abhorrent that human life is so coldly dismissed? Personally, I believe the bible speaks to this issue and calls it murder. I could attempt to address what she wrote and what many in favor of abortion believe by quoting scripture verses like: Exodus 20:13 – Thou shall not murder; and Exodus 23:7 – Have nothing to do with a false charge and do not put an innocent or honest person to death, for I will not acquit the guilty. But recently I saw a video by pastor Matt Chandler from The Village Church, which I feel addresses the issue very well. The video is at https://youtu.be/absW29h8kGA
Or if you would like to see the full sermon it is available at http://thevillagechurch.net/resources/sermons/detail/the-sanctity-of-human-life/
Also at the same link above is the transcript you can read if you prefer.
One last point. God doesn’t acquit the guilty, but if we put our trust in Jesus, He gives us the free gift of Jesus righteousness. HE wipes away our sins when we ask Jesus to be our Lord and Savior, because HE laid those sins upon Jesus and our sins were paid in full by Jesus at His death on the cross. Thus our guilt wasn’t acquitted, but paid for by Jesus.
