Samson does not appear to give any regard to the Lord. He does not cry out to the Lord. And he does not note that the only way he could break out of the city as he did was because God had given him the strength to do so. As far as he was concerned, he was perfectly capable of taking on the Philistines. This was a very dangerous attitude, which would eventually lead to his fall.1
Yet in spite of his playing with his calling, the Lord has not forsaken him. He is patient with Samson. He graciously delivers him.
3 But Samson lay till midnight, and at midnight he arose and took hold of the doors of the gate of the city and the two posts, and pulled them up, bar and all, and put them on his shoulders and carried them to the top of the hill that is in front of Hebron.
