These days we tend to think of "roads" as smooth swaths of pavement and judge them by how fast we can drive cars on them. A "path" is something different, suitable only for walking or maybe bicycles, and a "way" has more to do with giving directions than any physical reality. When we get "lost" it usually means we're in a car on an unfamiliar road -- a far cry from being in the middle of a trackless wilderness with no idea which direction to go. The ancient world was very different, with isolated towns and endless square miles of trackless wilderness. Then a "way" was a set of landmarks to follow to get from one place to another through the wilderness. A "path" was a way used enough to leave a visible trace on the ground, and a "road" was a heavily used path, easily followed and walkable. So it makes sense that when used in the Bible, all three terms represent guiding truth, ideas that lead us where we want to go. This is pictured in the modern use of "way" -- when we talk about the "way" to do something or the "way" to get somewhere. We're talking about the correct, best, most efficient method of doing something or getting somewhere. And it's good information -- truth -- that helps us find that best way.

Most of the time, falling means a lowering in spiritual state, from one closer to the Lord to one further. But, as with other common verbs, the meaning of "fall" is highly dependent on context in regular language, and in the spiritual sense as well. People fall on their faces in prayer, fall in battle, fall on others to attack them and fall on each other's necks in greeting. Stars fall from the sky, mountains fall on people, cities fall, and even faces fall. There's a lot of falling, in very different circumstances. When people fall on their faces in prayer -- it shows humility, and an acknowledgement of their own low state and need for the Lord's help. When they fall on each other's necks, it means a communication between the two spiritual states. At the other end of the scale, it illustrates complete spiritual destruction in the fall of a city.
