Hebrews 12:7-11 New International Version (NIV)

⁷ Endure hardship as discipline; God is treating you as his children. For what children are not disciplined by their father? ⁸ If you are not disciplined—and everyone undergoes discipline—then you are not legitimate, not true sons and daughters at all. ⁹ Moreover, we have all had human fathers who disciplined us and we respected them for it. How much more should we submit to the Father of spirits and live! ¹⁰ They disciplined us for a little while as they thought best; but God disciplines us for our good, in order that we may share in his holiness. ¹¹ No discipline seems pleasant at the time, but painful. Later on, however, it produces a harvest of righteousness and peace for those who have been trained by it.
