The Old Testament was a shadow of what was to happen in the New Testament. The period of the sojourn of the Israelites in Egypt was over but Pharaoh was reluctant to let them leave, even God told Moses that Pharaoh would not let them go unless compelled by a mighty hand, and compelled he was!
God instructed the Israelites to kill a spotless lamb; called the Passover lamb i.e. “a sacred cover” and use the blood to mark the entrance of the house, both the lintel and doorpost. V 13 “Now the blood shall be a sign for you on the houses where you are. And when I see the blood, I will pass over you; and the plague shall not be on you to destroy you when I strike the land of Egypt”. What this meant was that God would be a protective covering upon any house that He sees the blood and will not permit the destroyer to enter such a house; because of the blood!
In the New Testament, the blood of Jesus took a more active role in the lives of whosoever accept Him as his Lord and Saviour, Colossians 1:13- 14 “Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son: In whom we have redemption through his blood, even the forgiveness of sins”. We were redeemed by the blood of Jesus, our sins are forgiven by the blood and the blood became a protective covering over as many that believe in Him.
It is your covenant right as a child of God to enjoy divine protection because Jesus; our Paschal Lamb has paid the ultimate sacrifice for our security. The death we should die, Jesus took it, the pains, the sicknesses, the diseases etc. He took them from us. So no sickness, disease, pain, discomfort etc. should be found on you. Devil will try to put it on you, and if you accommodate it, it will be there but the moment you understand your covenant right of protection, you will reject them and they just have to leave your body.
Prayer point: Because Jesus has paid the price of protection for me, all sickness in my body, you are strangers there, I command you to leave right now in Jesus’ name.
