“Circumcise therefore the foreskin of your heart, and be no more stiffnecked .”
My Notes
What Does Deuteronomy 10:16 Mean?
Moses commands what no physical procedure can accomplish: "Circumcise the foreskin of your heart." Physical circumcision was already the covenant sign (Genesis 17). Moses says the external sign isn't enough. The heart — the seat of will, desire, and devotion — needs the same surgery.
"The foreskin of your heart" is a metaphor for the barrier around your inner life that prevents God's word from penetrating. The physical foreskin is removed to expose what's underneath. The heart's foreskin is the resistance, the hardness, the callousness that keeps you from being fully open to God.
"Be no more stiffnecked" adds the companion image: a stiff neck is an animal that refuses to turn when the master pulls the yoke. The uncircumcised heart and the stiff neck work together — one can't receive the word, the other won't follow the direction. Both need to change. And both changes require you to participate: circumcise. Stop being stiff.
Reflection Questions
- 1.What 'foreskin of the heart' (barrier, resistance, callousness) needs to be cut away in your life?
- 2.How does the command to circumcise your heart (your participation) relate to God's promise to do it for you (Deuteronomy 30:6)?
- 3.Where is your neck 'stiff' — where is God pulling and you're refusing to turn?
- 4.Does the gap between physical circumcision (the sign) and heart circumcision (the reality) describe your faith — signs without substance?
Devotional
Circumcise your heart. Cut away what's blocking you from God. Not your body — your heart.
Moses takes the most defining physical practice of the covenant — circumcision — and says: the real surgery isn't on your body. It's on your heart. The physical sign you carry is meaningless if the internal barrier is still there. The foreskin of the heart — the callousness, the resistance, the hard layer that prevents God's word from reaching the soft tissue underneath — needs to be cut away.
This is the Old Testament anticipation of the new covenant. Jeremiah will say God will write the law on their hearts (31:33). Ezekiel will say God will remove the heart of stone (36:26). Paul will say real circumcision is of the heart, by the Spirit (Romans 2:29). But Moses says it first: circumcise the foreskin of your heart.
The command is to you: circumcise. This isn't something God does to you in this verse (though Deuteronomy 30:6 says He will). This is something you participate in. You choose to cut away the resistance. You decide to expose the soft heart underneath the hard layer. You stop being stiffnecked.
The stiff neck is the companion problem: an animal that won't turn. You can see the direction God is pulling. You can feel the yoke. But your neck is so stiff that you keep plowing the same furrow no matter how hard the master tugs.
Two surgeries. One on the heart (cut the barrier). One on the neck (stop resisting the direction). Both are about openness: an open heart that receives the word and a flexible neck that follows the lead.
Circumcise. Soften. Turn. The external sign was never the point. The internal reality is.
