I think this applies to apologetics as well as literal war. We can do more damage than good with apologetics. It’s kind of like chemotherapy. We attack that which is unhealthy but there is a risk of destroying the healthy as well. So allow some room if someone’s ego gets hurt or if they start to look “desperate”. You do not want to push them farther away.
Apologetics is really not all that glamours. It’s like working a potato farm. But instead of planting seeds your job is just to throw out all the rocks in the soil. Sure there may be some seeds we plant but we really are not doing apologetics when we do this. We also must remember that we are not the one that converts the heart. That is the Holy Spirit’s job.
