2 Corinthians 10:4-5

10:4 for the weapons of our warfare are not human weapons, but are made powerful by God for tearing down strongholds. We tear down arguments 10:5 and every arrogant obstacle that is raised up against the knowledge of God, and we take every thought captive to make it obey Christ.

2 Corinthians 10:10

10:10 because some say, “His letters are weighty and forceful, but his physical presence is weak and his speech is of no account.”
