I have always been struck by the story of Samson. I remember reading his story in Judges when I had first become a follower of Jesus, and I rememeber being very inspired by his sacrifice. Samson was brought to complete humiliation by his own pride, selfishness, and lust, but was not overcome by his failings. He allowed God to transform him even if for just a moment, that he might return to following God, wherever it lead (even to death).
That final scene of Samson bracing himself on the pillars and pushing with every bit of strength left in his broken body, with full knowledge that if he succeeded he would surely die… Epic!
