Passover was observed to commemorate Israel's deliverance from Egypt (Exodus 12 ). The lamb was slain, but not a bone was to be broken (Exodus 12:46 ). Typified how "Christ our passover is sacrificed for us" (1 Corinthians 5:7 ). (Compare: John 19:36 ). While the very paschal lambs were being prepared He gave His life for us (John 13:1, 18:28 ). On the evening before the regular feast He and His disciples were gathered together to keep the feast which Jesus transformed into the first Lord's Supper.

1 Corinthians 10:16 "The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ?"

We celebrate the new covenant in His blood.

Luke 22:19 "And He took bread, gave thanks and broke it, and gave it to them, saying, 'This is My body which is given for you; do this in remembrance of Me.'"

Our teaching and worship is intended by God to emphasise deliverance from sin by the shedding of Christ's blood on the cross.

All leaven had to be completely taken from the camp, the day before eating the Passover, called the day of preparation. The feast continued seven days, speaking of purity expected of a redeemed people living a life free from the leaven of sin.

1 Corinthians 5:7-8 "Therefore purge out the old leaven, that you may be a new lump, since you truly are unleavened. For indeed Christ, our Passover, was sacrificed for us. Therefore let us keep the feast, not with old leaven, nor with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth."

Having been cleansed by Christ's blood we must now practice the unleavened life - walk in holiness. That is a perpetual festival of sincerity and truth. Sincerity refers to purity of motive in service, and truth to purity of action in service. In our teaching and worship the unleavened life of separation needs to be emphasised.

Connected with the two feasts named. This waving of the sheaf of firstfruits indicated that the whole harvest to follow belonged to God - consecration. It spoke of Christ the firstfruits.

1 Corinthians 15:20 "But now Christ is risen from the dead, and has become the firstfruits of those who have fallen asleep."

Christ's resurrection was presented to God as an earnest or prototype of the resurrection of all His people. Teaching and worship is God's intention - needs to emphasise living the consecrated new life to God. Christ's resurrection guarantees ours.
