Many people are reluctant to confront another person. Conflict avoidance is more common than conflict seeking. We all worry that our words will not be received properly. God never avoids conflict because He knows that He is right and His words always produce fruit. If we know we are speaking God's truth in a situation and have the other person's best interest in mind, then we shouldn't struggle to have confidence to speak the truth.
Lord, when I know that I am speaking out of love and for the best interest of another, help me to use your words and not my own.
