Love isn’t always embracing what someone does.
Everything Jesus did while He was on the earth He did in love.
That includes the time He sat down, wove a whip, and used it to chase the money changers out of the temple.
Discipline is a part of love - it teaches right from wrong and protects both the one being disciplined and those they might hurt.
You can speak the truth in love - which can still look like “what you’re doing is evil, repent or you’re going to hell”.
