In the book of Numbers, we see that it took 40 years to take Egypt out of Israel, because they refused to trust God even though He proved worthy of their trust. The people spent most of their time complaining about every move God made, they were unhappy, ungrateful and defeated followers of God because they were unwilling to slay their biggest foe, themselves.
Deuteronomy takes place in the final month of Moses’ life at 120 years of age and is made up of the three final sermons delivered by him to a new generation who were either too young to remember or not born yet when Moses first brought forth the commandments at Mount Sinai 38 years earlier.
Though only one month of it is a message of remembrance spanning God’s faithfulness through those 38 years to encourage a new generation to trust God so that they can enjoy the blessings of all His promises. Folks, it’s a sad fact that most of our anxiety stems from our failure to recall God’s faithfulness toward us in the past. Moses seems to be aware of this and has taken his final three sermons to remind the new generation that if one forgets God’s faithfulness in the past we are doomed to miss His faithfulness in the present and the future as well.
