Numbers 25 is the crazy story of a priest driving a spear through an adulterous, idol-worshipping couple, and in so doing, turning aside the wrath of God from the whole community of Israel. We learn that at the root of all sin is idolatry, that sin is serious and so making atonement for sin requires extreme measures. And so we are prompted to consider what idols we are yoking ourselves to, to confront sin in our lives and what it will take to cut sin off, but it also causes us to be amazed at what God has done for us in Christ, and to look forward to a new creation where we will no longer battle with sin.
