Before you act and react out of emotions, consider seeking God for instruction and direction. You may be surprised at how he tells you to handle that situation.
“Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come. He shall glorify me: for he shall receive of mine, and shall shew it unto you.”
John 16:13-14 KJV | King James Version
