By His Spirit
Our battles are won not with our might, nor our power, but by the Spirit of the LORD. Let us submit to the Holy Spirit within us. You have already won a victory over those people, because the Spirit who lives in you is greater than the spirit who lives in the world. (See 1 John 4:4)
But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ Jesus from the dead will also give life to your mortal bodies through His Spirit who dwells in you. —Romans 8:11 (NASB)
