For though we walk in the flesh,
we do not war according to the flesh,
for the weapons of our warfare are not of the flesh,
but divinely powerful for the destruction of fortresses.
2 Corinthians 10:3,4 NASB
"Therefore, put on the full armor of God, so that you will be able to resist in the evil day, and having done everything, to stand firm." Ephesians 6:13
