Don't know who John Bell is, but this quote of his is a good statement of divine purpose:
You keep us waiting. You, the God of all time, want us to wait. For the right time in which to discover Who we are, where we are to go, Who will be with us, and what we must do. So thank you … for the waiting time.
Except perhaps for the last part, about what we must do. That has been fully revealed in Scripture.
