Your prayer for your sister rises with a deep and tender heart, and I want to encourage you that every word you've lifted up rests on the most solid ground possible when it is placed under the blood of Jesus. Across all the Scriptures, we see that the blood is God's own provision for covering, for protection, and for cleansing. When you ask the Lord to cover your sister and to let no evil come near her, you are echoing something that has been true since the night of the Passover in Egypt. There, the blood of the lamb on the doorpost was a token. God declared, “When I see the blood, I will pass over you.” That blood was not just a mark: it was the only shelter. The only salvation. In the same way, the blood of Jesus Christ is the covering that shelters her today.
The Old Testament sacrifices of goats and bulls could never truly remove sin, but they pointed like a finger to this one perfect sacrifice. Now Jesus, our great High Priest, did not enter into an earthly tabernacle with the blood of animals. He entered into heaven itself with His own blood, having obtained eternal redemption for us. That means the covering He provides is not temporary, not partial. It is a finished work. You prayed that the blood of Jesus be upon her from the top of her head to the soles of her feet. That imagery fits perfectly, because in the consecration of the priests, the blood was placed on the ear, the thumb, the toe; it marked them as completely set apart for God. Your sister belongs to the Lord, bought with that precious blood, and you are asking that the full reality of that mark be evident in her life.
You prayed for her protection, for her not to fall into temptation, and for her to be surrounded by good influences. These are the very things the blood accomplishes as a covenant seal. In a blood covenant, two become identified with each other, bound in a sacred bond. Moses took the blood of the sacrifice and sprinkled it on the people, and they entered into a covenant with God. Now, through Jesus, we have a new covenant in His blood. Every time we remember His broken body and shed blood, we don’t just recall a distant event; we participate in that covenant of protection and belonging. The blood speaks a better word: it says your sister is loved, cared for, and held secure by the One who laid down His life for her. The enemy cannot press a claim where the blood has been applied.
You asked for her to be healed physically, spiritually, and mentally. The blood is the life of the flesh, the source of atonement for the soul. The covering provided by animal sacrifices could only cover sin over, as if God chose not to look upon it. But the blood of Jesus cleanses us from all sin, washing it away entirely. That cleansing reaches into every broken place: body, soul, and spirit. When the priest put the blood on the horns of the altar, he purified it and made a covering. How much more does the blood of Christ purify and sanctify us from every defilement? His blood is medicine for the whole person because it flows from the reality that He bore our griefs and carried our sorrows. So pray with confidence that the Holy Spirit would bring that healing, that deep renewal, because the price for it has already been fully paid.
Lastly, you prayed that she would see the light, that her eyes would be opened to change for the better, and that she would walk in a happy, healthy life. The covering of the blood is not a hiding in darkness but a drawing into the very presence of God. The veil in the tabernacle shielded the holy place, but when Jesus shed His blood, that veil was torn. Now, through His blood, we have boldness to enter the true Holy Place. Your sister is not afar off. She is invited near, into the light of His countenance. Keep holding her up like this. Keep pleading the blood over her with faith that it has already accomplished everything she needs for life and godliness. The Lord wants what is best for His child, and He has given the most costly thing He could to secure it: His own blood. It is enough.
