Don't hate your brother
Recently, I had to tell someone close to me a very hard thing. (He calls himself a Christian.)
I shared the following with him:
“Do not hate a fellow Israelite in your heart. Rebuke your neighbor frankly so you will not share in their guilt” (Lev 19:17).
I won’t go into the details but I said even if I have to tell him he’s wrong a hundred times, it’s better to do that than hate him in my heart.
