Your best friends will criticize you privately and encourage you publicly.
There is a place for constructive criticism, and we all need it. None of us is above the objective, truthful, and loving correction of someone who has our best interests in mind. This is where your friends come in.
What kind of friends do you have? Do you have friends who will tell you the truth in love (Ephesians 4:15), or do you surround yourself with people who tell you what you want to hear? If these are the only friends you have, they are probably not your friends at all, because even though they talk nice in front of you, they’re talking about you behind your back.
Your best friends will level with you, even at the risk of alienating you for a while. They will tell you privately where you’re wrong and where you need to straighten up, as long as you let them know ahead of time that you want the truth.
“I am warning you! If another believer sins, rebuke him; then if he repents, forgive him.”
