How a person’s mind works is seen in their actions, which are a result of the conclusions the mind makes. By taking the word for mind and adding a specific ending, the Greek language is expressing the result of the working of the mind, so not just the thoughts, but the conclusions resulting from our thoughts.
As Christians, we are not to be ignorant of the workings of Satan’s mind (2 Corinthians 2:11). In Scripture, the methods that he uses are revealed to us (Ephesians 6:11); therefore, we are to stand firm against him. He also blinds the results of the working of the mind for those who do not believe (2 Corinthians 4:4). When presented with the truth of Scripture, the suppositions of those blinded are incorrect. A good example with this is the Gospel for Salvation, which is clearly stated in 1 Corinthians 15:1-4. Yet how many “gospel” tracks modify the message of the gospel to “repenting of your sins”, “making Jesus the Lord of your life” and so on, which are different gospels that are not good news at all (Galatians 1:6).
Due to Israel’s rejection of God’s covenant of promise and seeking their own righteousness, even today, when they read the Old Testament a veil covers the mind (2 Corinthians 3:14) so they do not understand and draw proper conclusions based upon what it states.
We have a renewed mind in Christ, a mind that can understand the things of the Spirit and produces correct suppositions based upon fact so it is able to discern what is the will of God (Romans 12:2). When we do not use this frame of mind, we can be led astray from the simplicity that is in Christ by those who seek to manipulate our conclusions by bringing another Jesus, another spirit, and a different gospel (2 Corinthians 11:3-4).
Because we are the children of God and are saved, His peace protects the suppositions of our mind so that we can live out the life we have in Christ (Philippians 4:7). We reside in this peace, an unruffled mind, by setting our mind on the things above and seeing things as they really are.
Our war is not a physical one, it is for the mind. By using the inherent ability God has given to us in Christ we are able to destroy strongholds within the mind while tearing down everything that is built up against the knowledge of God so that we are making correct conclusions based upon facts, not assumptions based upon false teachings.
For walking in flesh, we do not wage war according to flesh, for the instruments of our warfare are not fleshly, but an inherent ability by the God facing destruction of strongholds while tearing down logics and every high thing lifting itself up against the knowledge of God and taking captive every conclusion of the mind unto obedience of the Christ – 2 Corinthians 10:3-5.
