Love For the Saints

(1) What is the effect of the Gospel? How do we know that 'Gospel-activity' has taken place?
(2) A disciple-defining love - radical, costly love for other believers.
(3) How is it possible for us to love in this way? By looking at Christ's love for us.
(4) The Gospel is free, but carries an 'oughtness' to love.
(5) The Gospel self-test of love, and proper motivation for loving one another.
