Passover memorialized and observed through Jesus Christ

Ezekiel 45:21

“In the first month, on the fourteenth day of the month, you shall observe the Passover, a feast of seven days; unleavened bread shall be eaten.” Ezekiel 45:21

This verse describes the beginning of the observance of Passover that would last seven days with the feast of unleavened bread. The observance of Passover and the feast of unleavened bread is one event. That is exactly how this is meant to be as quoted in the following verses, “‘So this day shall be to you a memorial; and you shall keep it as a feast to the Lord throughout your generations. You shall keep it as a feast by an everlasting ordinance. Seven days you shall eat unleavened bread. On the first day you shall remove leaven from your houses. For whoever eats leavened bread from the first day until the seventh day, that person shall be cut off from Israel. Exodus 12:14-15 Today, the Jewish culture has turned this into two festivals, back-to-back, to create 14 days of festivities. The seven days of Passover festivities come first, and at its end they celebrate another seven days for the Feast of Unleavened Bread.

Exodus 12:1-28 explains the observance of Passover.

The observance of Passover is much more than a time of people gathering together for 14 days of festivities. This is a time of observing the blood that Jesus Christ [the unblemished Lamb of God] shed on the Cross to atone for our sin. With His blood applied to our heart, death passes over us and we are granted life. “For indeed Christ, our Passover, was sacrificed for us.” 1 Corinthians 5:7 “For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.” Romans 6:23

This is how our Lord Jesus Christ wants us to observe the Passover, “Now on the first day of Unleavened Bread, when they killed the Passover lamb, His disciples said to Him, “Where do You want us to go and prepare, that You may eat the Passover?”…In the evening He came with the twelve…And as they were eating, Jesus took bread, blessed and broke it, and gave it to them and said, “Take, eat; this is My body.” Then He took the cup, and when He had given thanks He gave it to them, and they all drank from it.  And He said to them, “This is My blood of the new covenant, which is shed for many. Assuredly, I say to you, I will no longer drink of the fruit of the vine until that day when I drink it new in the kingdom of God.” Mark 14:12, 17, 22-25 “This is My body which is given for you; do this in remembrance of Me.” Luke 22:19

In Exodus, the blood of the lamb was put on the two doorposts, the one to the left and the one to the right, and on the top door beam [lintel]. And they shall take some of the blood and put it on the two doorposts and on the lintel of the houses…” Exodus 12:7 The placement of the blood forms the shape of the Cross, where our Lord Jesus Christ shed His blood as the sacrificial Lamb of God to atone for sin. Exodus was written about 1450 years ago before the birth of Jesus Christ, before a cross was even used as an executioner tool.

The picture below shows the sign of the Cross after the blood of the lamb was applied to the left and right doorposts and the top door beam. This is similar to how some people express their prayer, they touch their head and then touch from side to side across their chest.
