Jim, you should worry if God doesn't send chastisements. His chastisments are a good thing and show his love. Sometimes a doctor has to cause pain to heal his patients, or a loving father to discipline his children.
Heb. 12:  For you have not yet resisted unto blood, striving against sin:  And you have forgotten the consolation, which speaketh to you, as unto children, saying: My son, neglect not the discipline of the Lord; neither be thou wearied whilst thou art rebuked by him.  For whom the Lord loveth, he chastiseth; and he scourgeth every son whom he receiveth.  Persevere under discipline. God dealeth with you as with his sons; for what son is there, whom the father doth not correct?  But if you be without chastisement, whereof all are made partakers, then are you bastards, and not sons. Moreover we have had fathers of our flesh, for instructors, and we reverenced them: shall we not much more obey the Father of spirits, and live?  And they indeed for a few days, according to their own pleasure, instructed us: but he, for our profit, that we might receive his sanctification.  Now all chastisement for the present indeed seemeth not to bring with it joy, but sorrow: but afterwards it will yield, to them that are exercised by it, the most peaceable fruit of justice.
From St. Thomas More's Dialogue of Comfort:
If chastisement is a good thing God does, I don't see why a "Great Chastisement" would be out of the question if there was a great need for chastising.
