It is the same with the will. A man has a will to jump. He can jump over a five-barred gate; but he cannot jump over a cathedral.
So with his will in moral matters. He has a will to resist temptation, but though he may clear a small temptation, he may fall at a large one.
The actions of a man's will are as mathematically fixed at his birth as are the motions of a planet in its orbit.
God, who made the man and the planet, is responsible for the actions of both.
As the natural forces created by God regulate the influences of Venus and Mars upon the Earth, so must the natural forces created by God have regulated the influences of Eve and the Serpent on Adam.
Adam was no more blameworthy for failing to resist the influence of Eve than the Earth is blameworthy for deviating in its course around the Sun, in obedience to the influences of Venus and Mars.
Without the act of God there could have been no Adam, and therefore no Fall. God, whose act is responsible for Adam's existence, is responsible for the Fall.
If God is responsible for man's existence, God is responsible for all Man's acts.
If a boy brought a dog into the house and teased it until it bit him, would not his parents ask the boy, "Why did you bring the dog in at all?"
But if the boy had trained the dog to bite, and knew that it would bite if it were teased, and if the boy brought the dog in and teased it until it bit him, would the parents blame the dog?
