The analogy that I gave earlier this week was that of a car and its alignment. If a car is in perfect alignment then it will travel in a straight line without someone turning the steering wheel. If a car is not in alignment then the car can be made to go straight with the steering wheel.
Both ways the car will travel in a straight line, but as I discussed on Monday, God is not concerned about the straightness of our path, but the internal alignment of our souls.
