In short this sutta is also called Subha sutta which was given to Subha by the Buddha. Subha asked Buddha what differentiates beings:
Short lived and long lived
Diseased and healthy
Ugly and beautiful
Powerless and powerful
Poor and rich
Low-born and high born
Ignorant and wise
This sutta gives specific examples of the fruits of kamma, good and evil, based on the layman notion of good begets good, evil begets evil.
Buddha told Subha: “Beings are owners of kammas, heirs to kamma, born in kamma, bound by kamma, have kamma as their refuge. It is kamma that differentiates beings into low and high state.” 1. Life expectancy

Conclusion At the end of the discourse, Subha praised Buddha for his excellent teaching. Just as if one were to place upright what had been overturned, were to reveal what was hidden, show the way to one who was lost and to hold up the lamp in dark so that those eyes could see forms; Buddha had made the dhamma clearer for Subha. Subha turned to the triple gem for refuge after the teaching.
