Paul's instruction is a four-generation discipleship model: Paul, Timothy, reliable people, others. That's legacy. That's how Kingdom impact scales beyond a single lifetime.
In business terms: who are you developing? Not just managing, not just assigning work to — developing. Who are you intentionally equipping to lead, to own, to eventually do what you do and more?
The leader who develops no one leaves nothing behind. The leader who develops many multiplies their impact through every person they invested in. This is Kingdom math.
Invest in formation early, shape toward strength and calling, and the investment compounds over time.
