The Passover was one of the most important observances for the Israelites. Every Israelite was expected to observe it. Much was done to prepare for the Passover.
All tombs in close proximity to Jerusalem were to be painted white during the month leading up to the Passover. It was a law that any person found dead in the field was to be buried where found. The tomb was to be painted white to caution anyone passing by not to touch the tomb. Otherwise, the person touching it would be unclean for the Passover.
Two weeks before the Passover, the flocks and herds were to be tithed. The Temple treasury chests were publicly opened and emptied. Then, many of the Israelites went up to Jerusalem to purify themselves. They did this to make absolutely sure they were spiritually clean for the Passover. They were not to eat of the Passover feast if they were unclean.
In 1 Corinthians 5:7, Christ is said to be our Passover. This means he is our sacrificed Lamb whose blood must be over us at the Judgment. In 1 Corinthians 11: 27-29, we read, “Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord. But let a man examine himself, and so let him eat of that bread, and drink of that cup. For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord’s body.”
It is very important that each person partaking of the Lord’s Supper make sure that he is spiritually clean. It is absolutely necessary to be spiritually clean when one observes the Lord’s Supper. The Lord’s Supper is very important. The bread and the juice represent the body and blood of Jesus. Just as the Passover was a very serious spiritual event, so is the Lord’s Supper. It is not to be taken lightly and without thought. Proper preparation and proper thought is to be given toward it.
Make sure you know how to properly examine yourself. Read and study God’s Word, the Bible. Help others know how to properly examine themselves. And if any of this is hard to understand, ask an adult to help you.
