Paul gives us an awesome reminder that the key measuring stick in serving the Lord is "that one be found faithful."  It is so easy to get caught up in success and not faithfulness.  But what the Lord challenges me with in regards to this reminder is in having wisdom to discern between real faithfulness as opposed to obstinacy or incompetence.  It is easy to persist and plod on in ministry where one gets confused for the other.  Lord give us the wisdom to grow into true faithfulness as the motivation of our service.
