As I read these verses from the author of Hebrews today, I was reminded that not everyone on earth has experienced the positive and loving discipline of an earthly father. Single moms face special challenges, and so do their children. Assumptions are dangerous. Remember not everyone has shared your life experiences or mine.
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! 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. 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. (Hebrews 12:9-11 NIV)
