The first part of chapter 10 deals with spiritual warfare. Note the language here: vs. 3 “war,” vs. 4 “weapons of our warfare,” “pulling down strongholds,” “bringing into captivity.” There is a lot of military language here.

The main verb in this passage seems to be “we war” (.3). So Paul is telling us here how he wages spiritual warfare. He’s ready to fight against the false teachers who had infiltrated the church.

Like Paul, we are engaged in a great spiritual struggle. Our situation is not the same as Paul’s, but we are part of the same war. We have the same goals as Paul. We use the same weapons in this spiritual battle. Hopefully, we don’t have to deal with false teachers; but if we did, Paul gives us an example of how to fight them.
