The Jewish Festival of Tabernacles (Booths/Tents) is one that reminds them of being in the wilderness and how God provided and led them through that time. In our own lives we go through times in the wilderness too, and we need help, just like the Israelites, to get through it. When Jesus attended this festival, He made it clear that He is the way through the wilderness, and that the festival was a reminder to be looking for Him!
John 7-8
The wilderness reminds us that Jesus is the only way to survive.
