Treating transformation as something that arrives someday is choosing death and calling it patience.
A new heart gets issued as an assignment rather than a gift, and the God who could simply install one puts the verb in human hands instead. Anyone who believes their heart is something done to them waits, waiting keeps the old behavior running, and behavior left running finishes them.
The question about dying attaches full pain to staying as they are, and pain attached to staying moves a person this week rather than next year. The casting away and the making new arrive in one breath because a vacancy refills with whatever used to live there. What it costs is the comfort of assuming there is time, and anyone who keeps that comfort keeps the old heart along with it.
