I know, we are months past the Passover and months more away from the next one, but this is still an important lesson.
Galatians 3 explains that the Old Testament was given to teach us. It’s amazing what you learn about New Testament concepts by studying the Old Testament.
Israel was in bondage for many years in Egypt. When God freed them, he did so by killing the firstborn of every household that had not taken the steps necessary to identify themselves as belonging to God through participation in the Passover. Exodus 12 goes into detail and explains that the only acceptable sacrifice was an unblemished male lamb. Those who failed to follow God’s instructions put themselves and their households in jeopardy. When the Israelites left Egypt, they were commanded to commemorate this Passover every year.
Jesus said in John 8:34 that all who sin are slaves to sin and Paul said in Romans 6 that we are enslaved by sin. Paul also said in Romans 6:23 that the wages of sin is death. Because of this, God celebrated a new Passover. He sent His son, the lamb of God without spot or blemish who “became our Passover” (1 Corinthians 5:7). It is through His blood that we have salvation (Romans 5:9, Ephesians 1:7, Colossians 1:20, Hebrews 10:19), and it is by participating in His death that we have a hope for eternal life in heaven (Romans 6:3-9). In Matthew 26 Jesus established the way by which we commemorate this new Passover, and we continue to do so today through the Lord’s Supper.
