26 While they were eating, Jesus took bread, and when he had given thanks, he broke it and gave it to his disciples, saying, “Take and eat; this is my body.” 27 Then he took a cup, and when he had given thanks, he gave it to them, saying, “Drink from it, all of you. 28 This is my blood of the covenant, which is poured out for many for the forgiveness of sins. 29 I tell you, I will not drink from this fruit of the vine from now on until that day when I drink it new with you in my Father’s kingdom.” 30 When they had sung a hymn, they went out to the Mount of Olives. (Matthew 26:26-30)
Here the Lord Jesus established the Holy Communion. The bread is the body of the Lord Jesus, and the cup is the blood of the Lord Jesus, the blood of the covenant, which was poured out on the cross for many for the forgiveness of sins.
19 And he took bread, gave thanks and broke it, and gave it to them, saying, “This is my body given for you; do this in remembrance of me.” 20 In the same way, after the supper he took the cup, saying, “This cup is the new covenant in my blood, which is poured out for you. (Luke 22:19-20)
The bread is the body of the Lord, which was sacrificed for us on the cross. We take Holy Communion to remember the Lord and His great love. The cup is the new covenant between the Lord and His disciples, which was shed for us.
53 Jesus said to them, “Very truly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. 54 Whoever eats my flesh and drinks my blood has eternal life, and I will raise them up at the last day. 55 For my flesh is real food and my blood is real drink. 56 Whoever eats my flesh and drinks my blood remains in me, and I in them. (John 6:53-56)
Here it says that eating the flesh of the Lord and drinking the blood of the Lord is to receive His life, to be united with the Lord, and to abide in him, and He abides in us. When a person repents and be baptized, it is the beginning of a new life, the beginning of union with the Lord. We should often draw near to the Lord and be united with the Lord, so that the Lord’s life can be in us.
42 They devoted themselves to the apostles’ teaching and to fellowship, to the breaking of bread and to prayer. (Acts 2:42)
Here it talks about the four things that the early church did: keeping the apostles’ teaching, that is, keeping the apostles’ biblical teachings, fellowship with one another, breaking bread, that is, receiving Holy Communion, and praying, not only praying in the church as a group when they gathered, but also drawing near to the Lord, praying on their own. May God bless you and your family!
