How Is Jesus Our Passover?

The last part of I Corinthians 5:7 reads "Christ our passover is sacrificed for us." What did Paul mean calling Jesus our passover? We all remember the original passover as recorded in Exodus 12. The text informs us the Israelites were to take the blood of a lamb and "strike it on the two side posts and on the upper door post of the houses." This was a token to God to pass over that house when He killed all the firstborn in Egypt (the tenth plague). In this way all the Egyptian households lost their firstborn, while the Israelite households did not.The analogy to Christ is that based upon His shed blood, God passes over us when it comes time to give us what we deserve for our sins (spiritual death, Rom 6:23). We can be so thankful for that, but we don't receive such benefit unless we meet God’s stipulated conditions - trust and obey (II Thess 1:8). Are you trusting and obeying God like you ought (Heb 5:9)?
