Revelation 12:11 And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death.
I love this verse. There is victory for us. Satan can not defeat us.
We have victory because of our salvation that was purchased by the blood of the Lamb. I am a new creature. My sins have been forgiven. I am accepted in the beloved. I have all of that the Bible promises me because of what Jesus has done! It is yours just by believing and accepting the free gift.
Being under the blood of Jesus is the basis for everything but you will have to step out and say it. It is your testimony. It is your acknowledging in your heart and publicly all that the Lord Jesus has done for you.
Then once you know who you are, have decided to unashamedly say so then you decide to not love your life. You realize that Jesus is your life. You are not living for you. You are living for Him. You are not seeking yourself but Him and His.
You have the victory. Just step up and take it!
