Hebrews 12:4-7

In your struggle against sin you have not yet resisted to the point of shedding your blood. And have you forgotten the exhortation that addresses you as sons? “My son, do not regard lightly the discipline of the Lord, nor be weary when reproved by him. For the Lord disciplines the one he loves, and chastises every son whom he receives.” It is for discipline that you have to endure. God is treating you as sons. For what son is there whom his father does not discipline?
