Matthew 5:16
In the same way, let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven.

For the weapons of our warfare are not of the flesh but have divine power to destroy strongholds. We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ.
2 Corinthians 10:4-5
