The letter of the Hebrews reminds us that life itself can get rid of some of the rough edges. These re the trials that it calls the discipline of the Lord. For Example, it is hard to be self-centred when there’s someone at home who needs constant attention. It is hard to be arrogant when a person is unemployed or loaded down ith debt or hit by illness. Life can put us into spiritual shape. Whether God send ssomehting into our life or allows it to happen, the person of faith knows tha thes have the grace to build spiritual muscle and make us ready for the kingdom.
