The Daily Nosh: Judges 3:1-2
(1)Now these are the nations that Adonai left, to test all Israel who had not experienced any of the wars of Canaan. (2) It was only in order that the generations of the sons of Israel might learn from war, which they had not experienced before. (TLV)
As clearly illustrated in this case, I try to remind myself that God may allow and use adversity as a necessary component to make me wiser and stronger, to preserve current success and position me for future successes.
