Revelation 12:11

“And they overcame him by the blood of the Lamb, etc.] The Lord Jesus Christ, by whose blood they were redeemed and ransomed out of the hands of Satan, that was stronger than they; and by which they were justified from all sin, and so all charges and condemnation were of no avail against them, whether of Satan or the world; and by which they were cleansed from all pollution, both internal and external; and by which even their conversation garments were washed and made white; by this they also, drew nigh to God with boldness, as to their own God, notwithstanding the accusations of Satan; and this they could, and did make use of as a shield to defend them against all his charges; and this being…”
