Let us clear up one thing straight away, Easter was a Pagan spring equinox festival until it was christianised in the 4th Century by the church to try and eradicate the Jewishness of the Bible from the church. You only need to read the history books to find that out. I know it says in the King James Bible : Acts 12:4 "And when he had apprehended him, he put him in prison, and delivered him to four quaternions of soldiers to keep him; intending after Easter to bring him forth to the people", but remember the King James Bible wasn't translated into English until the end of the 15th Century, or early 16th. By that time the Church Fathers had changed virtually all the Jewishness of the Bible so that they could control the masses. It is the reason Henry 8th got rid of the Roman Catholic Church because he wanted the power instead of the church over the masses and the same reason why the Pilgrim fathers sailed to Plymouth Massachusetts and eventually founded the USA.
Passover, one of the Feasts of the LORD, first given in the book of Exodus chapter 12, the Hebrew word is Pesac which has a literal meaning of "Protection, cover". When you read the Exodus chapter, the meaning is very apt and literal for the Jews at that time. The last plague out of the ten brought on the Egyptians to free the people of Israel from slavery, the death of the First Born. The Israelites are given strict instructions about what they must do to escape the plague coming on them. Each house must select a 1 year old lamb, sacrifice that lamb and eat all the meat before the following morning. They are also told to apply the blood of the door posts and lintel.
John1:36 John the Baptist SAys "Behold the Lamb of God" when he sees Jesus. John is saying and pointing you to Passover with this reference. Jesus was crucified on Passover. Taking part in Communion is actually taking part in the Passover meal. In Revelation5:12 Jesus is referred to as the Lamb of God and is referred to by that name of the Lamb 29 times in the book of the Revelation. The Lamb sacrificed at Passover to atone for the sins of the world as the first Lamb was sacrificed on the first Passover to protect the house from the plague.
In 2020 both the Passover and the Christian Easter line up date wise. But that is not where the similarities end. As the plague went through the land of Egypt, God commanded his people to stay in their homes under His protection. The US President, Donald Trump has called the Covid 19 virus a plague just days before the start of Passover and Easter. Most of the world has been quarantined in their homes and told to stay indoors by their various governments so that the virus, plague, might pass us by. OK we didn't have to sacrifice a lamb and paint the door posts with blood but you have to admit we do have a astounding resemblance.
In Matthew chapter 9 we are told "I want you to have mercy", both the Greek and Hebrew translation of the word mercy is grace. We should not celebrate or be glad if someone dies from the virus, the same as the Israelites did not celebrate to death of all the first born Egyptians.
We must also remember that once the Passover had finished the Israelites were told to go, they left the Land of Egypt and the Egyptians even gave them gold and silver as they were leaving.
As I have already mentioned the Book of Revelation above, have you noticed that the plagues that fell on Egypt are mentioned as the same plagues that will fall on the world in Revelation. The first Passover account in Exodus can be used as a shadow picture for what is to come, Pharaoh is a symbol of Satan, Egypt is a symbol of the World, Israel a symbol of the Church and the Lamb is Jesus. I will also ask a question for you to ponder, if you have got this far, where was Israel when the plagues fell?
Think about this, if the blood of a 1 year old Lamb can protect a household from the angel of death during that first plague, then what can the blood of Jesus do for you?
King James Bible : John 4:22 "Ye worship ye know not what: we know what we worship: for salvation is of the Jews."
