Rev12:10-11. And they overcame him by the blood of the lamb and by the word of their testimony.
In biology, we were told that those in the blood group 'O' are universal donors while some are recipients. I'm more concerned about why someone has to donate his blood. Jesus was the first blood donor to the universe for the cleansing of sins, He is a universal donor.
Someone humorously said that's the reason why we sing 'O' the blood of Jesus.
What can wash away my sins? Nothing but the blood of Jesus. I know you know that song. Apply the blood on your dirty past&life, and go and sin no more.
If there are corrections to make from your past, please go and make those corrections&apply the blood to overcome guilt, pain and shame. His blood works for anyone&everyone IF applied.
CONFESSION: Father, I overcome by the blood In Jesus Name.
