Holy and godly lives

What can we take from today's reading?  We should live holy and godly lives.  Peter writes this in terms of how to react to the coming destruction of the world and the end of time, and we should always be mindful that this life isn't the end of the journey.  It's only the beginning, the training ground.  And since we don't know when our time is up, we should make every effort to live holy and godly lives at all times, so that we are ready.
