It can be difficult to talk about sin (yours or someone whom you are close to) but that is often how the Holy Spirit convicts and convinces us to change.
Pray The Word and Prepare for The Word
Mark 6:20 - Herod was greatly disturbed whenever he talked with John, but even so, he liked to listen to him.
Read - Matthew 14:1–5; Mark 6:17–20; Luke 3:19–20
John the Baptist had lived such a life that the secular leaders confused Jesus with him. Now that is a good goal. Live in such a way that people are pointed to Christ by your life.
Lord, I will listen to You about my sin and speak up when blatant sin is present.

John the Baptist saw sin for what it was…something that separated a person from God, led others astray and ultimately Marred a life so that it was unrecognizable in comparison to what God had planned. Seeing this, John would not be silent even if it was one of the most powerful families on the planet. Does the pain of sin cause you to act and speak against it with those around you? You can do that without being a prude or a judge. You can do it in such a way that makes clear your heart desire is simply to help a person avoid the deceiving, dividing and destroying Marring of Sin.
