Patience when the kids forget their lunch money for the fourth day in a row. Patience when one-third of the class fails the test. Patience when the text books haven't arrived yet, and the semester starts tomorrow. We often use words carelessly and with much too much familiarity.

To be bound is to set limits, to be headed in a determined direction, obligated, compelled and even fettered to the point of becoming one in essence with an idea or plan.

He guarantees the bound, the payment for crimes committed. Paul was making the statement that the preaching of the gospel could not be stopped by chains or imprisonment.
