Proverbs 27:9-10
When a friend gives you a heart felt counseling session, (or you give a friend one) it’s a good thing. Most of the time they don’t say things on purpose to hurt you. When you know they're being 100% genuinely heart felt, then God loves it too!
As far as verse 10 goes & abandoning friends, I both agree and disagree. There can be some friendships that are toxic and not helpful for you. If they are always putting you down, mistreating you, or taking advantage of you, they aren’t good friends anyway.
The best of friends ARE there anytime a disaster strikes your life. They will be with you not matter what, pointing you to God and His Word. That’s what real true friends do. Of course, we should do that for our friends as well.
