Some points that may be worth developing

  1. Being a disciple means more than just "hanging out with Jesus."
     (From
    http://onefamilyoutreach.com/bible/Mark/mk_09_38-50.html)
  2. Test of discipleship is in life, both individual action and the quality of communal life.
  3. Having salt in yourselves probably means living in the mutual loyalty of the covenant relationship.
  4. From the James lesson:
    One of the essential qualities of Christian community is centrality of prayer.
  5. From the Esther lesson:
    Action without specific reference to God can nonetheless be godly action.

Working theme:
God's work as we experience it may be based in the church, but is not limited to any one church, or even to the wider church. Let there be no triumphalism among Christians!
