Nomadic life is very common in the Old Testament or Torah. The Bible records forty years during which the Israelites traveled through the desert on their way to the Promised Land. When God needs you to arrive at a certain place, his methodology is to keep you in motion, though not necessarily in nomadic motion.
Nomads had several things in common. They were without a permanent resting place; their meals were uncertain; they never knew when they would be able to stop traveling and set up camp; and they always had a new destination planned. I suspect that many of God's people will become nomads and refugees as they flee from war torn countries or states, seeking refuge for themselves and their families. We may not enjoy the nomadic lifestyle, but many valuable lessons can be learned if you are ever forced to live it today.
First, never tell anyone that you have no permanent place to live because they will tell you that if God is on your side, he will provide you a place to live. That is true in heaven where God is in control. It is not true on earth where Satan is still in control. Second, if you are ever unable to afford a meal, take a quarter out of your pocket and give it to someone less fortunate. Third, if you arrive at a place that does not have flowing water, keep moving. Fourth, if you ever arrive at a place that feels like home, you can set up a "permanent" camp. However, know that at any moment, you may be required to move again, because in the "real" world, nothing is ever permanent.
We all are nomads and refugees, whether or not we think of ourselves in this manner. We may not move as frequently as the average nomad or refugee, but whether we move from one home to another, or change employment, we are constantly in motion. We are in motion because we are energy and as with water, energy must remain in constant motion. When the goal is a lofty destination, more energy and more motion is required. But God promises that the rewards will be worth the sacrifice.
