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 12:11
In Hebrews 12:4-11 the writer describes God’s discipline in the terms of a parent disciplining their children. He even goes so far to say that if God is not disciplining you in some way shape or form then you are not truly his children. He concludes this section on God’s discipline with today’s verse. In it he starts off by stating the obvious that all discipline seems painful at the time that is received. He then goes to say in the same verse that if the discipline that you have received is used correctly then it will produce good results. What the writer is telling us is that we by nature want to avoid pain and unpleasantness and discipline by its nature is painful and unpleasant. So when we are disciplined for doing something that is against God’s will he is using our very nature to help us avoid those situations in the future. That is the meaning of the phrase “for those who have been trained by it”. Let God’s discipline in your life work the right way and don’t just think of it as punishment, but think of it as God training you to know what to avoid so that you can live your life to the fullest.
