Revelation 12:11 (ESV) 11 And they have conquered him by the blood of the Lamb and by the word of their testimony, for they loved not their lives even unto death.
Notice the wording here, “we have” not “will” or “potentially could”; We HAVE conquered Him. This Scripture reminds us of who we are in Christ and, in that, what it means to use both the Blood of the Lamb and the Word of our Testimony to live a life of victory against Satan and all his plans.
