JR Miller wrote on the blood of Christ,
A quaint old man used to carry a little book which he took very often from his pocket, and which he called his "biography." It had only three pages, and there was not a word written on any of them; yet he said the little book told the whole story of his life!
The first page was black--that was his sin, which was his condition by nature. He would shudder whenever he looked at it.
The second page was red--that was the blood of Christ, and his face glowed when he gazed upon it.
The third page was white--that was himself washed in Christ's blood, made whiter than snow.
His book told the whole story of every redeemed life. Between the black of our sins, and the white of redemption--must always come the red of Christ's blood.
"The blood of Jesus Christ cleanses us from all sin!" 1 John 1:7
