Hebrews 12:3-6

Consider him who endured such opposition from sinners, so that you will not grow weary and lose heart. In your struggle against sin, you have not yet resisted to the point of shedding your blood. And have you completely forgotten this word of encouragement that addresses you as a father addresses his son? It says, ‘My son, do not make light of the Lord’s discipline, and do not lose heart when he rebukes you, because the Lord disciplines the one he loves, and he chastens everyone he accepts as his son.’
