Where's the focus?

At the heart of the Sermon is a section on spiritual disciplines because Jesus expects his disciples to practice charity, praying, and fasting. Jesus, however, doesn’t command almsgiving, prayer, or fasting but assumes them. The central issue that provokes Jesus is an act done to be noticed as pious and to gain a reputation. Disciplines are done with eye, heart, mind, and soul focused on God.— Sermon on the Mount, page 195
