Understand part 1 before part 2
A number of years ago, my mother came to visit with us for several days. I thought she might like a particular movie, so I rented it. After thirty minutes of watching the movie, my mom said, “I’m sorry, but I just don’t understand this movie at all.”
I picked up the video case and realized I had mistakenly rented part 2, the sequel to the movie, instead of the original movie, part 1. She couldn’t understand part 2 because she hadn’t seen part 1.
In same way, we can’t comprehend Part 2 (the Lord’s Supper) until we first understand Part 1 (the Passover Feast). The Old Covenant is part 1. They killed a Passover Lamb and ate the Feast of Unleavened Bread to remember their deliverance from
Jesus ended Part 1 and replaced it with Part 2.
The New Covenant is part 2. Jesus became the Passover Lamb (1 Cor. 5:7). We are to partake of the Lord’s Supper to remember our deliverance from our sins.
This is My body
Show the congregation a picture of your wife and say, “This is my wife. Actually, this picture really isn’t my wife because she’s sitting right there.” Then point to your wife.
When Jesus held up the bread at the Last Supper and said, “This is my body,” He meant it was a picture of what He would do on the cross, not that it was His literal body, which they could see was holding the bread. He was giving them an object lesson to remember His sacrifice. "Do this in remembrance of Me" (Luke 22:19).
