In verses 5 and 10, God adds emphasis by referring to “the house of bondage” to remind His people of their former lack of freedom. Reading between the lines, these passages imply that failing to heed this warning will result in a return to slavery, because serving any god but the true God is slavery.
Verses 1-5 warn against allowing a prophet to influence us to serve a different god. But this goes a step further, because notice that in verse 5 it says, “to entice you from the way in which the LORD your God commanded you to walk.” That includes serving the true God in a way other than how He instructs. God gives a specific way, and that way is defined by His commands, His judgments, and His statutes. So, just saying the Creator is our God, or that Jesus is Lord, or Christ is King, is meaningless if we do not also walk in the way He says to walk, without adding to it or subtracting from it. That’s the proof that He is our God and that we love Him—that we not only honor Him with our lips but that we conform our lives to every word that proceeds from His mouth.
First, a prophet does not have to wear a robe and sport a long beard. In the broadest sense, a prophet is a spokesman or a representative of some kind. The word means, “one who speaks for another.”
Second, while the term “wonder” indicates something miraculous, the word “sign” does not have to depict anything supernatural at all. It can mean a mark, or more broadly, an indicator. It can mean some sort of proof, or something that can be observed, regardless of whether it involves the supernatural.
Third, remember that God’s concern is not only Who is worshiped, but also how the worship takes place, meaning whether it is in alignment with the way that God commands us to walk.
Putting this together, this passage not only warns against something as obvious as someone calling fire down from heaven, like the False Prophet of Revelation, but in principle, it covers scenarios that are much more subtle and commonplace.
Notice that God commands the death penalty here. Now, I am not advocating stoning your local mega-church pastor—let me be clear on that. God has not given the church the same civil authority that He gave to the physical nation, and He certainly has not given that authority to church members. But the death penalty here shows that God is deadly serious, not just about which God is promoted, but also whether the message lines up with the way in which God commands us to walk.
Just to reemphasize our focus here, this is all in the context of having been delivered by God, and striving to remain free of spiritual slavery. The upshot of Deuteronomy 13 is to very carefully evaluate the voices and the teachers and the teaching that we allow into our lives that could undermine the way of God and lead us back into the house of bondage.
