Jesus is the new Pascal Lamb whose sacrificial flesh and blood brings us forgiveness of sins (Matthew 26:27-28), and seals God’s new and everlasting covenant with us (Luke 22:20). Therefore, unless we eat His flesh and drink his blood, we will not have life within us (John 6:53). He told His disciples that He is the living bread that came down from heaven; and the bread that He will give them for the life of the world is His flesh (John 6:51). He gave them this bread at the last supper saying, “Take, eat: this is my body” (Matthew 26:26). In His old covenant God wrote His words (Exodus 20) on stony tablets. The people were to follow the written words and prosper. In the new Covenant, God became flesh (John 1:14) and sacrificed His life to save us from sin (Matthew 26:27-28). Furthermore, He feeds us with the bread and wine, which are His sacrificial flesh (John 6:51) and blood of the New Covenant (Luke 22:20) so that we may have Eternal Life (John 6:54). In doing this He imprints His Words on our hearts (Jer. 31:33) to change our stony hearts to natural heart (Ezekiel 11:19). This means that believers follow God’s laws, not because they are laws, but because, they are the desires of their heart. In other words, their heart desires what God desires.
To make His sacrificial body and blood ever-present to us and to make His New Covenant eternal He commanded His apostles to celebrate His Supper as often as possible (Luke 22:19). This celebration is the wedding feast of the Lamb (Revelation 5:6) in which Christ unites with His people. This celebration fulfills what Malachi had prophesized (Malachi 1:11): “from the rising of the sun even to the going down, my name is great among the Gentiles, and in every place there is sacrifice, and there is offered to my name a clean oblation”. By partaking in this meal we establish a communion of life with Christ (John 6:56). Is not this personal relationship with Christ?
