Romans 12:2 Don't become so well-adjusted to your culture that you fit into it without even thinking. Instead, fix your attention on God. You'll be changed from the inside out. Readily recognize what he wants from you, and quickly respond to it. Unlike the culture around you, always dragging you down to its level of immaturity, God brings the best out of you, develops well-formed maturity in you.
If life is like a game of chess then we must never be so quick to tip our King in defeat. We must never surrender to the enemy. The story of Samson in Judges 13-16 has nothing do with him but everything to do with God. His life is a living lesson in the grace of God. How a man who was beaten, blinded, humiliated by his own repeated sin, reached the bottom, turned around and discovered that God was waiting for him all the time. There is nothing heroic about Samson. He did nothing but serve himself. In the end all he did was turn around and found out God was still there. God is the hero of the story.
