Q. How do we take our thoughts captive in Christ? Are there words that must be said? Do we invoke Jesus’ name? Do we just try to think of something else? Do we pray to have satan bound in Jesus’ name so he cannot affect us? How do we know If the thoughts are from an evil entity or just our sin nature? What is the correct way to deal with thoughts that cross our mind and are not holy and serving of God
A. We take thoughts captive by concentrating on Scripture that refutes the thought, replacing evil with good in our minds. It’s an application of the theory of displacement which holds that two objects cannot occupy the same space at the same time. At the conscious level we can only think one thought at a time, so focusing on the good thought will force the bad thought out of our mind. It doesn’t matter whether the thought comes from the devil or from our own sin nature, it’s all the same.
In Phil 4:8 Paul told us, Whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things. By doing so we can take evil thoughts captive before they can enter our mind and take root there.
