The people have reached Mount Sinai. The mountain where it all began–just as God had promised when He first appeared to Moses in a burning bush:

I will be with you, and this shall be a sign for you, that I have sent you: when you have brought the people out of Egypt, you shall serve God on this mountain.

The promise is being fulfilled. The time has come for them to meet the God they will serve. Will they obey His voice? Will we?
