As you know, Passover begins at sundown on Monday, April 18. It is a time of celebration that commemorates the deliverance of the ancient Hebrews from slavery in Egypt. You can read about it in Exodus 12.
The Lord said, "For I will pass through the land of Egypt this night, and will smite 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.
"And the blood shall be to you for a token upon the houses where ye are: and when I see the blood, I will pass over you, and the plague shall not be upon you to destroy you, when I smite the land of Egypt.
"And this shall be unto you for a memorial; and ye shall keep it a feast to the Lord throughout your generations; ye shall keep it a feast by an ordinance for ever....And ye shall observe the feast of unleavened bread; for in this selfsame day have I brought your armies out of the land of Egypt: therefore shall ye observe this day in your generations by an ordinance for ever....
"And the Lord said unto Moses and Aaron, This is the ordinance of the Passover: There shall no stranger eat thereof....All the congregation of Israel shall keep it" (Exodus 12:1-47).
The Passover this year is occurring as we commemorate the 150th anniversary of the beginning of the War Between the States--the war that enabled African-American slaves to go free.
It would be accurate to say that Passover is a celebration of freedom--a commemoration of God-given liberty, but it is so much more than civil liberty. Passover is also a celebration of the spiritual liberty God has given to us.
"For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death" (Romans 8:2).
Because of the blood of Jesus Christ we are free indeed. God said, "When I see the blood [of Jesus] I will pass over you." We are free from sin, condemnation, and Satan's power because of the blood of Yeshua Hamaschiach.
