19 Even when the cloud stayed over the tabernacle many days, the Israelites carried out the LORD's requirement and did not set out. 20 Sometimes the cloud remained over the tabernacle for [only] a few days. They would camp at the LORD's command and set out at the LORD's command. 21 Sometimes the cloud remained [only] from evening until morning; when the cloud lifted in the morning, they set out. Or if it remained a day and a night, they moved out when the cloud lifted. 22 Whether it was two days, a month, or longer, [b] the Israelites camped and did not set out as long as the cloud stayed over the tabernacle. But when it was lifted, they set out. 23 They camped at the LORD's command, and they set out at the LORD's command. They carried out the LORD's requirement according to His command through Moses. Numbers 9:19-23

I like this little story of what the Israelites went through. They had no clue whether or not they would get to stay anywhere for more than a night. They always had to be ready to move. It’s like that for us as well. We can have a general idea of what direction God wants us to go in life, but until He directs us, we don’t have a clue what to do. We have to rely on Him to take care of tomorrow. So don’t worry! :D
