And they overcame him by the blood of the Lamb

.... and by the word of their testimony, and they did not love their lives unto death (Revelation 12:11). The 'him” referred to,  is the accuser of the brethren (Satan verse 10) who “has been cast down” (past tense). The scene then is in the future,  looking back on the the ones who overcame i.e. the  victorious church. Christ promises many things to those who overcome,   they will: eat from the tree of life; not be hurt by the second death; be given a new name, some of the hidden manna,  power over the nations,  white garments and to not be blotted out of the book of life;  be confessed before the Father and the angels; be made a pillar in the Temple of God and granted to sit with Christ on His throne (2:7, 11, 17, 26; 3:5, 12,  21).

Great rewards, but who is sufficient for these things?  Paradoxically (and wonderfully) in the Kingdom it is in weakness that we, like Christ,  overcome and become more than conquers (Romans 8:37).  He came as a little helpless baby, and He was crucified in weakness.  But He now lives by God's power (2 Corinthians 13:4). and  invites us to share in that overcoming resurrection  power (Philippians 3:10). It is His strength in us, operating through us, and it is made perfect in our weakness  (2 Corinthians 12:9; Philippians 4:13).  And the foundation, the  end and the beginning of it all,  is “by the blood of the lamb.”  The Lamb of course is Jesus, the “lamb of God that takes away the sins of the world” (John 1:29).  And this redemption (the buying us back from the slave market of sin) is through His shed blood (Revelation 5:9; John 8:34).

Having secured our salvation by His blood, we are set free from the fear of not measuring up, of death and of Hell (Romans 8:1). And we are equipped to be His Ambassadors to this wicked and hurting world (2 Corinthians 5:20). As ambassadors we overcome the Evil one by the word of our testimony,  and like Jesus,  not loving our lives unto death (Philippians 2:8).  These two things go very much together. In other words our living for Christ is part and parcel of our testimony.  If our lives do not match our words,  we are not living according to the truth, and are in fact living a lie  (1 John 1:6). It is not that we will ever be perfect in this life, but it is our goal, and as we spend time in His presence we are being transformed from glory to glory (2 Corinthians 3:18). In other words it's the journey that is important here. But after we have set Christ apart in our hearts we also need to be ready and prepared to give an answer (in words) of the hope that is within us (1 Peter 3:15). Nobody is saying this is easy in this climate of intimidation. It is however essential in overcoming the accuser!

Father thank You for the security of salvation (1 John 5:13), that allows us to go forward with boldness, knowing with Paul that the process of overcoming is indeed a process, and that though we have not attained perfection,  nevertheless it motivates us  press on towards the mark of the high calling to which You have called us (Philippians 3:12-14). We want to glorify You Lord,  in Jesus Name Amen
