Deuteronomy. Take no prisoners.

If we were thinking about the mightiness of God in Chapter 6, then Chapter 7's instructions to 'take no prisoners' are no surprise. Anything that seeks to combat God and His people is to be destroyed. So Chapter 7 is full of instructions as to what to do with enemies and the idols they worship.

God is unique, having dominion over ALL creation. He does not ask us to ignore those things which lure us away from worshipping him, but to destroy them so that we worship HIM to the exclusion of all else.

Enemies are anything which seek to divert our attention and devotion away from God. If we vigorously seek, with God's almighty strength to help us,  to combat them, then we will remain in God's will and be blessed. We can do this - loosen the hold of the idols which lure us away from God - by setting our minds and hearts on Him, dwelling on his amazing character and goodness, setting our hearts apart to cherish Him:

"Do this because you are a people set apart as holy to God, your God.God, your God, chose you out of all the people on Earth for himself as a cherished, personal treasure.

God wasn’t attracted to you and didn’t choose you because you were big and important—the fact is, there was almost nothing to you. He did it out of sheer love, keeping the promise he made to your ancestors.God stepped in and mightily bought you back out of that world of slavery, freed you from the iron grip of Pharaoh king of Egypt. Know this:God, your God, is God indeed, a God you can depend upon. He keeps his covenant of loyal love with those who love him and observe his commandments for a thousand generations. But he also pays back those who hate him, pays them the wages of death; he isn’t slow to pay them off—those who hate him, he pays right on time.

So keep the command and the rules and regulations that I command you today. Do them.

And this is what will happen: When you, on your part, will obey these directives, keeping and following them, God, on his part, will keep the covenant of loyal love that he made with your ancestors:
He will love you,
he will bless you,
he will increase you."

So "Do not be terrified by them, for the Lord your God, who is among you, is a great and awesome God."

When we do this, then, as Peter Jobes says, we can more easily share the news of the truth of God, offering answers to people hurt and broken by the pursuit of the idols of our time.
