For though we walk (live) in the flesh, we are not carrying on our warfare according to the flesh and using mere human weapons. For the weapons of our warfare are not physical [weapons of flesh and blood], but they are mighty before God for the overthrow and destruction of strongholds.
2 Corinthians 10: 3-4
“Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers; But with the precious blood of Christ, as of a lamb without blemish and without spot.” —1st Peter 1:18,19
