The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ. 2 Corinthians 10:4-5
Notice these two things, first, we are in a “fight” and second our weapons have divine power. The “fight” is described in terms of arguments, knowledge, and thoughts so it’s a battle that takes place in our minds. The divine power of our weapons tells us that we can win this fight.
What goes on in our mind is important in spiritual terms. Our thoughts, our focus, our attitudes significantly impact how we live. If we’re focused on all that is wrong in the world we will be weighed down and discouraged. If we focus on God’s mighty power, his purposes and plans for the world, we will have hope.
This verse tells us that we don’t win the battle in our minds by our own efforts. We need the divine power that is available to us through Christ. God has made sure we are fully equipped to handle every situation. Yet we need to draw on his resources by faith, believing that God will supply all our needs. Often we don’t feel able to control our thoughts. They seem to bombard us and overwhelm us. But his promise is, “He will not let you be tempted beyond what you can bear” (1 Corinthians 10:13).
As we believe God has equipped us, despite how we feel, we will learn to focus our mind on, “Whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable …” (Philippians 4:8).2 Corinthians
