The true disciple does not serve himself or the “public”, but his
Lord, in simplicity and generosity: “And your Father who sees
everything in secret will reward you” (Mt 6,4.6.18).  Our fitness
will always be more effective the less we seek our own glory
and the more we are aware that the reward of the righteous is
God Himself, to be united to Him, here, on a journey of faith,
and at the end of life, in the peace light of coming face to face
with Him forever (cf. 1 Cor 13:12).
