I explained abortion to my kids this year. They are 10. They are incredulous that any human would participate in this act.
They are both adopted.
One of my sons is also adopted. He is currently in his rebellious stage and has loudly opposed all my values except one - he is pro life. I still remember the day when we had the news on and there was a story about abortion — he turned to me with wide eyes and said “mom, that could have been me”
That moment has apparently stayed with him as well. I think this is the issue God will use to bring him out of his rebellion and back in the fold.
