When death came by the homes with blood on the entrances, it went on by to another home. This is telling us a truth. We must apply the blood of Jesus to our lives. Therefore, I died. When death comes to claim us, it looks and sees blood and that tells him that we already died.
Death has nothing to claim.
The Bible teaches that it is appointed unto man ONCE to die. Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord. These verses tell us that people only have to die once. Now, the lamb died instead of the Hebrews in Egypt. But that did not matter.
