Toward the end of Deuteronomy before Israel crosses over into the promised land, God gives a song to Moses which is intended to be a sharp reminder in the people’s ear of their wickedness and proneness to sin. But more importantly, it’s stark contrast to God’s mercy and grace on his people.
Deuteronomy 31:19-21:
"Now therefore write this song and teach it to the people of Israel. Put it in their mouths, that this song may be a witness for me against the people of Israel. For when I have brought them into the land flowing with milk and honey, which I swore to give to their fathers, and they have eaten and are full and grown fat, they will turn to other gods and serve them, and despise me and break my covenant. And when many evils and troubles have come upon them, this song shall confront them as a witness (for it will live unforgotten in the mouths of their offspring). For I know what they are inclined to do even today, before I have brought them into the land that I swore to give."
The song, which comes in the following chapter, is delivered to be a reminder and to deliver conviction to the wandering soul. God has been merciful, yet is a God of wrath.
This, of course, reminds me of my own inclination to please myself and my own constant need to remember the Gospel of Jesus, which is given for similar reasons yet from a very different direction.
The Gospel reminds us not only that we are sinful beings, and that God is a God of wrath, but also that he is gracious and patient. It is not his wrath that will lead us to repentance, but his grace! Remembering this can give us the confidence and strength to stand and trust God to sanctify us and conform us to his own image.
About a year ago I posted a review of a book by Milton Vincent called A Gospel Primer for Christians.
The book’s aim is this very thing. To help Christians remember the basic, strength giving, tenets of the Gospel. It begins with an explanation of the Gospel and concludes with a simple rehearsal of those truths for Christians to remember on a regular basis.
For me, this book has been a great blessing toward this end. It’s usually less than $10 and worth every penny.
Much like Moses’ song delivered to Israel to remind them, we can use similar tools to remember Jesus’ Gospel and find strength to move foreword even in the face of our own opposition.
