Blood

It happened at the first Passover celebrated by the Hebrew people in Egypt. At the eating of the lamb and the painting of their doorposts with blood, their deliverance from slavery by the hand of God was seen. The Angel of Death passed from house to house - except from the houses of those who were obedient to the Word.

The Lord Jesus came to the world as the Lamb of God. He came to save and to free the captives of the devil. He determined the salvation and freedom for all. Those who accept Him as Lord are covered by His blood, which is able to deliver them from eternal death. Since that sacrifice, those who are enslaved and oppressed by devil will only be free if they have the mark of the Son’s blood imprinted on their hearts. Death is sweeping across the land and leading souls to eternal death; and you friend, do you have the mark of the blood?

"For the Lord will pass through to strike the Egyptians, and when he sees the blood on the lintel and on both doorposts, the LORD will pass over the door and will not allow the destroyer to enter your houses to strike you." Exodus 12:23

NOTE: Do not live by appearance, only looking to please other; look carefully, He said: "on both doorposts," - inside and outside the door - which means that you need to have a heart of God.
