Thought
The pattern of the behavior of the Israelites (and in fact, the pattern so familiar to all of us, sadly) can be seen early in their journey into the wilderness. It went like this: 1) God does something amazing and they worship Him; 2) time passes, things get hard, and they forget how amazing God is; 3) they have doubts or give up on God and look for help from other sources. It is hard for humans to remain faithful. But the more we know about God and the more we spend time with Him, the easier it is for us to remember to worship Him only.
