God’s promise to Israel before their entry into the promised land, included health and healing. God promised to bless their bread and water. Water supplies were not as sophisticated during those times and there were no modern methods of purifying water for consumption. Nevertheless, God promised to bless their water and the food that they would eat. This was so that they would not become ill from polluted water or contaminated food.
Earlier in the same chapter, God made them a promise saying, “If you will diligently listen to the voice of the Lord your God, and do that which is right in his eyes, and give ear to his commandments and keep all his statutes, I will put none of the diseases on you that I put on the Egyptians, for I am the Lord, your healer” (Exodus 15:26). The Jews would have observed many illnesses overcome the Egyptians during the plagues. God used these signs to force Pharaoh to release his people from bondage.
It can be hard for people to be around sickness and diseases and not become fearful. What God was reminding his people was that, the state of sickness and infirmity was not their portion. God’s people were covered through the blood covenant and the angels of death passed over their doors. The Passover covenant was established when the death angel moved through Egypt. God’s people put the blood of an animal on their doorpost and this acted as a seal of protection.
Jesus Christ became the ultimate sacrifice for mankind, so that we no longer have to use the blood of animals to protect us. The blood of Jesus Christ speaks life and is a better sacrifice than animals. As his children, our salvation brings us into this blood covenant which acts as a seal of protection. The blood covers you at work; covers your home and your family; covers your finances and covers your health. Sickness and disease is not our portion and we do not have to be sick a day in our lives.
We are healed through the blood of Jesus Christ and his blood covers us. “And they have conquered him by the blood of the Lamb and by the word of their testimony” (Revelation 12:11). Jesus took our sins and every infirmity and disease and he nailed it to the cross. “But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed” (Isaiah 53:5).
