2 Corinthians 10:1-6

¹ By the humility and gentleness of Christ, I appeal to you—I, Paul, who am “timid” when face to face with you, but “bold” toward you when away! ² I beg you that when I come I may not have to be as bold as I expect to be toward some people who think that we live by the standards of this world. ³ For though we live in the world, we do not wage war as the world does. ⁴ The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. ⁵ 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. ⁶ And we will be ready to punish every act of disobedience, once your obedience is complete.

Romans 8:5-8

⁵ Those who live according to the flesh have their minds set on what the flesh desires; but those who live in accordance with the Spirit have their minds set on what the Spirit desires. ⁶ The mind governed by the flesh is death, but the mind governed by the Spirit is life and peace. ⁷ The mind governed by the flesh is hostile to God; it does not submit to God’s law, nor can it do so. ⁸ Those who are in the realm of the flesh cannot please God.
