For I will pass through the land of Egypt on that night, and will strike all the firstborn in the land of Egypt, both man and beast; and against all the gods of Egypt I will execute judgment: I am the Lord.
Now the blood shall be a sign for you on the houses where you are. And when I see the blood, I will pass over you; and the plague shall not be on you to destroy you when I strike the land of Egypt. [Exodus 12:12-13 NKJV]
This is an excerpt from one of the best known stories in the Old Testament. This story, where The Lord sent the destroyer to strike the Egyptians, but protect the children of Israel, shows the event which has ever since been commemorated as one of the three Great Feasts of Israel - The Feast of Passover - which we celebrate as Easter.
Easter was apparently named after a pre-Christian goddess of Spring, Eostre, referenced by The Venerable Bede, and is probably another example of early Christian saints converting an existing belief system to Christianity. St Columba's footprints at Keil in Kintyre, originally used for ceremonial purposes, almost certainly pre-dated Columba, as did a similar carving on Dunadd near here.
But the Easter message is so much more than history and the workings of men - fascinating though a lot of that is. All that is in the world, while The Lord works in the land, and this is His way of doing that ...
Moses called for all the elders of Israel and said to them, “Pick out and take lambs for yourselves according to your families, and kill the Passover lamb.
And you shall take a bunch of hyssop, dip it in the blood that is in the basin, and strike the lintel and the two doorposts with the blood that is in the basin. And none of you shall go out of the door of his house until morning.
For the Lord will pass through to strike the Egyptians; and when He sees the blood on the lintel and on the two doorposts, the Lord will pass over the door and not allow the destroyer to come into your houses to strike you.
And you shall observe this thing as an ordinance for you and your sons forever. [Exodus 12:21-24 NKJV]
... The Lord works the land - which is each of us - as would a farmer. He sows and plants and tills the soil; He nurtures the growth, but is not afraid to weed out where necessary. He is creating His garden anew, and we can see this husbandry right throughout scripture, right throughout the history of this world; right throughout the life of each one chosen by Him since before the beginning of time to be His people.
'He sees the blood on the lintel and on the two doorposts'. The Lord sees those who follow Him; who know Him. Those who hear His word; who hear Him. They are 'covered in the blood of Jesus'
Much more then, having now been justified by His blood, we shall be saved from wrath through Him. [Romans 5:9 NKJV]
Hallelujah! And may God give you of the dew of heaven, of the fatness of the earth, and plenty of grain and wine at this blessed Eastertide.
