Argue your case with your neighbor, but do not reveal someone else’s secret.
Proverbs 25:9 (EHV)
One of the fundamental principles of counseling is confidentiality. Whatever the counselee tells you, it is crucial to never reveal what they tell you in private. What often happens is that, to justify himself, this same person will not hesitate to reveal the secrets of others. The hardest part of all of this is hearing Christians say that they don't trust another Christian because they are too quick to reveal their secret.
Do you have a friend who you would never dare to tell a secret to because you know that he will end up revealing everything one day, especially if he find himself in a difficult situation in which he needs to justify himself? You are not the only one. The Bible teaches us today that revealing other people's secrets is a bad thing, even though it can help us make strong arguments. In doing so, we will attract the wrath of others and consequences will follow.
As it says in verse 10, even the person to whom you revealed the other's secret will shame you. Perhaps by saying that you are not a trustworthy person or by turning directly to the victim. As Christians, we must follow Paul's teachings that we are to walk in the spirit and we will not fulfill the lusts of the flesh. This will save us from being outrageous.
May the grace of God be with you all.
