Deuteronomy 32:1-9 English Standard Version

1 “Give ear, O heavens, and I will speak, and let the earth hear the words of my mouth.
2 May my teaching drop as the rain, my speech distill as the dew, like gentle rain upon the tender grass, and like showers upon the herb.
3 For I will proclaim the name of the Lord; ascribe greatness to our God!

4 “The Rock, his work is perfect, for all his ways are justice. A God of faithfulness and without iniquity, just and upright is he.
5 They have dealt corruptly with him; they are no longer his children because they are blemished; they are a crooked and twisted generation.
6 Do you thus repay the Lord, you foolish and senseless people? Is not he your father, who created you, who made you and established you?
7 Remember the days of old; consider the years of many generations; ask your father, and he will show you, your elders, and they will tell you.
8 When the Most High gave to the nations their inheritance, when he divided mankind,
he fixed the borders of the peoples according to the number of the sons of God.

9 But the Lord’s portion is his people,Jacob his allotted heritage.

For those of us that view Deuteronomy as nothing more than legal demands, let me offer up that these words as both commentary and prophecy.

Galatians 5:19-21 English Standard Version

Now the works of the flesh are evident: sexual immorality, impurity, sensuality, idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions, envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God.

1 John 4:7-11 English Standard Version

Beloved, let us love one another, for love is from God, and whoever loves has been born of God and knows God. Anyone who does not love does not know God, because God is love. In this the love of God was made manifest among us, that God sent his only Son into the world, so that we might live through him. In this is love, not that we have loved God but that he loved us and sent his Son to be the propitiation for our sins. Beloved, if God so loved us, we also ought to love one another.

For the moment allow me to parse the nature we are born with and address only anger, rivalries, dissensions, divisions, and envy. These things inherently oppose love.

We need not teach a child to do any of those things and merely need to emphasise them as facts of life. Generational hatred is easy to foster because the flesh readily accepts its own nature.

Love on the other hand is not taught. Love needs to be shared and experienced in a manner where its benefits outweigh the alternatives.

Ephesians 3:19 and to know the love of Christ that surpasses knowledge, that you may be filled with all the fullness of God.
