The Spirit of the Lord came powerfully upon him. The ropes on his arms became like charred flax, and the bindings dropped from his hands. Finding a fresh jawbone of a donkey, he grabbed it and struck down a thousand men.
Samson wasn't particularly righteous. He was sexually immoral, flippant towards God's law, fairly deceitful, and foolish in his dealings with women. No, Samson wasn't righteous, but he was available. He was ticked off at the same people God was ticked off at, and he was willing to fight. When his greatest military victory came he had been bound with ropes by his own people and handed over to the Philistines. He had no weapons at his disposal and was surrounded by his enemies. But when God's Spirit rushed on him Samson was given supernatural strength. He broke free of his bonds as though they were nothing and looked around for any weapon he could lay a hand on. What he found was the jawbone of a donkey and with it he killed one thousand men.
One of the many lessons we learn from Samson's life is that God can do impossible things through imperfect people. This is what God has done all throughout human history. He used Martin Luther to stand alone against a Catholic Church that had become so corrupt that it actually sold salvation. He used William Tyndale to translate the Bible into English from the original Greek and Hebrew texts even as the Catholic Church in his country said common Christians didn't need to read the Bible and persecuted and hunted him. And were it not for God's work in William Carey's life the modern missions movement might have never started and millions of souls might be lost to Hell. In his lifetime, Carey was a lone voice arguing that Christians still have a responsibility to take the good news of Jesus to the nations. God used him to start a movement.
None of these men were perfect, but they were all aligned with God's will for their lives. Each of them stepped out in faith and acted. If you and I will do the same, then God will accomplish all He pleases through us. Who knows what the great author has written for you in His book? Will you preach the gospel, feed the hungry, clothe the naked, fight for the oppressed, start a movement, or raise up the next generation of Christians? Only God knows and only you can find out, if you'll step out in faith and see.
