The Body of Christ is often talked about in the abstract or more metaphorically. But it is really a concrete reality and literal in the spiritual realm and stepping into the physical realm of how we love God and love each other in our obedience to Him and our works done in faith. How we live as Christians effects other Christians in a very real way that we must remember always. We do not operate in isolation as believers but as a part of a Body that is dependent on that Body and especially the Head of that Body. And what others do effects us as well.
Abolitionist Eric Robinson gives a great talk on this and I highly recommend that you take time to listen to this and test it against the Scriptures.
Abolition is very much about the Body of Christ working together to bring an end to abortion.
