pass it on

Please clarify the following in red.

"My personal motto... comes from my mother," she says. "When we were kids she drilled this into our heads: 'To whom much is given, much is expected.' We didn't have material wealth, but we were blessed and fortunate and had every opportunity presented to us and with that, came the obligation to pass it on."

What does "it" refer to? Every opportunity? Does it mean the obligation to pass it on to the next generation?

Thank you.

It refers back to this in 'she drilled this into our heads'.

Does it mean the obligation to pass it on to the next generation?

Yes.
