In preparation for the Lord’s Passover (Ex 12:11), we’re to choose a spotless lamb to represent our house and keep it for four days, a lamb for each household. (Ex 12:3) At this stage it’s any blemish free lamb, a generic lamb.
Once a lamb is selected, a determination is made as to which household(s) it represents. Then a lamb becomes the lamb (Ex 12:4), the one lamb to represent the household(s) for which it is chosen.
Once the lamb-to-household relationship is established, the lamb becomes your lamb. The family spends time getting to know their lamb, verifying that it has no blemish. (Ex 12:5) They inspect it, and become deeply familiar with it. Then, in place of their own firstborn, they kill their lamb on the 14th day. (Ex 12:6)
As in all God’s feasts, He’s giving us a window, a picture, a hint of how to walk with Him.
Jesus Christ is not just a passover lamb; He is not just the passover lamb. It’s not enough to know that Jesus is a savior, one among many. Neither is it enough to know that Christ is the savior, the one and only. Yeshua, Jesus Christ of Nazareth, the Jewish Messiah, must become our passover (1Co 5:7); until He is our savior, whom we have chosen for ourselves, to represent our souls in the day of judgment, getting to know Him, and He us, we have nothing. (Mt 7:21-23)
Let’s choose Christ deliberately and deeply, giving diligence to make our calling and election sure (2Pe 1:10), getting to know everything about Him that we can (Php 3:10), personalizing His work and connecting with His nature and character. Let’s behold the beauty, feed in the majesty, and enjoy the unfathomable riches of Christ! (Eph 3:8)
During the four days leading up to Passover, when we’re supposed to be inspecting our lamb and becoming intimately familiar with it, it makes sense to fulfill this aspect of the feast by inspecting our Messiah daily, meditating on Him and examining Him very carefully, and enjoying again His absolute perfection.
