How Does Jesus Keep Cleansing You With His Blood?
“The high priest brought the blood from the Holy of Holies and sprinkled the earthly altar for incense and the earthly altar for burnt offering (Heb 9:21). In this way he cleansed and consecrated these most holy things. Jesus, the great High Priest, sprinkles the heavenly things with his blood (Heb 9:23); with his own blood he sprinkles the hearts and consciences of those who serve the living God in the heavenly sanctuary (Heb 9:13–14; 10:2, 22; cf. 9:9). In his Holy Supper he brings his blood from his Father’s presence and gives it to his guests to drink for their cleansing and sanctification. Thus, as Pfitzner has shown, Jesus performs an “ongoing ministry of atonement” by the application of his blood on his people.”
