Just saying that modern things and modern knowledge are sometimes better than the understandings of 4000 years ago.
Like if someone wants to come at me with a sword then go for it. The result will be very predictable for me.
And what if you have a boil on your skin? Do you want to lance it and then treat it with antibiotics or do you want to do as Isaiah advised in Isaiah 38:21?
“Let them take a cake of figs and apply it to the boil, that he may recover.” I'm sure this was good advice in Isaiah's time.
You two keep fig cakes in your medicine cabinets, right?
Do you use oil and wine for open wounds as per Luke 10:34?
You see where I'm going here?
As for Matthew 18 I'm just saying I've seen it abused. And when people invoke it my discussion always starts with: "Are you sure you're right and the accused is wrong?"
