In Hebrews 12:3-29 we are given a description of Kingdom Life, that is  the way of life that we are to pursue as those who, in Christ, are  receiving a KIngdom that cannot be shaken (10:28). Once again the writer  reminds us of our privileges and responsibilites. As sharers in the New  Covenant we are part of the heavenly church and part of the family of  God. Therefore we are to fight sin and pursue holiness. In this God’s  loving discipline (instruction) is critical.
