Many of us are familiar with the Passover that the Israelites observed every year to remember how God delivered them from Egypt. Thinking about this, I can understand why God wanted to preserve this event in their memory. He was preparing them for Jesus Christ.
At the last plague, God told His people to kill a lamb without blemish and paint its blood on their doorpost. In doing this, the angel of death would pass over them. Whoever was without the blood of the spotless lamb would die.
Jesus became our passover lamb. He actually died at the same time of Passover to signify this. Simply put is this, if we have the blood of Jesus (whom is the Lamb of God without blemish or spot) then death will pass over us. If we do not have His blood, then we will die.
Jesus was speaking to Martha at her brother's burial and said "..whosoever liveth and believeth in me shall never die. Believest thou this?" (John 11:26)
I used to be puzzled when I read that verse of Jesus speaking to Martha. I thought well.. we all still die regardless. How could He say that we will never die? Later, God revealed to me that He was speaking of the second, true and final death in the end. For us who are in Christ, we shall never die and this is truth.
When our flesh dies, God considers it as "sleep." The Bible always refers our physical death as sleep because it is temporary. We shall all awaken and rise.. some unto the resurrection of life, and some unto death. (John 5:29)
But when God speaks of death .. He speaks of the second death that is to come. This is the true death. The wages of sin is death. In the end, those without the lamb's blood shall surely die just as the death of the Egyptians revealed this. Did they burn alive in agony forever and ever, or did they die?
I hope that we all will be reminded of this glorious event.. seeing how God designed the plague of Moses to testify of Christ, and brought in His Son which fulfilled it all. This is the significance of Christ being the Lamb of God. Is He on your doorpost?
