Take a sprig of hyssop, dip it in the bowl containing^[a] the animal’s blood, and wipe the blood on the doorposts and the beam above the door of your house. Not one of you is to leave the house until morning.When the Lord goes through Egypt to kill the Egyptians, he will see the blood on the beams and the doorposts and will not let the Angel of Death enter your houses and kill you.You and your children must obey these rules forever.When you enter the land that the Lord has promised to give you, you must perform this ritual.When your children ask you, ‘What does this ritual mean?’you will answer, ‘It is the sacrifice of Passover to honor the Lord, because he passed over the houses of the Israelites in Egypt. He killed the Egyptians, but spared us.’” – Exodus 12:22-27 GNT

I link my experience and acceptance of the power of the blood of Jesus through my Pentecostal upbringing. This passage was the very first part of the practice of having a covering.

It was important to know that no one was saved by prayer nor saved by fasting. Salvation is only by substitution – trusting Jesus as Saviour because He is the One who died in the place of every person. We are saved not because of any righteousness in ourselves but because we placed our trust in Jesus Christ, who then became our righteousness.

The application of the blood then was not about being spared in Egypt because of praying and fasting or because of their own merits but because they obeyed God and applied the blood to the door frames of their homes as God instructed.

I still find myself going into a new home, buying a new car, going into a hotel room, or sleeping overnight as a guest and taking the time to pray the blood, touching every wall, door and ceiling and giving that room to Jesus. There are great testimonies of those who have used the blood of Jesu to wage serious war against spiritual enemies and God fought for them. I am protected from destruction and from any attacks.
