Victory

 In you, O Lord, do I take refuge; let me never be put to shame! In your righteousness deliver me and rescue me; incline your ear to me, and save me! Be to me a rock of refuge, to which I may continually come; you have given the command to save me, for you are my rock and my fortress. Rescue me, O my God, from the hand of the wicked, from the grasp of the unjust and cruel man. For you, O Lord, are my hope, my trust, O Lord, from my youth. Upon you I have leaned from before my birth; you are he who took me from my mother's womb. My praise is continually of you.

Psalm 71:1-6 (ESV)
 
David learned to be faithful to God. He had learned that he could not rescue himself, that his enemy was too great, and that his ability to defend was too small. David's stability in life did not come from his circumstances but His God.
 
Too often, we think the victories in this life belong to us when they belong exclusively to God. We, too, should thank Him.
