1. DOWNWARD: The Lord’s Supper is a Means of Grace From God to the Church
For I received from the Lord what I also delivered to you, that the Lord Jesus on the night when he was betrayed took bread, and when he had given thanks, he broke it, and said, “This is my body which is for you. Do this in remembrance of me.” In the same way also he took the cup, after supper, saying, “This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.” For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes.
(1 Corinthians 11:23-26 ESV)
2. UPWARD: The Lord’s Supper is an Act of Worship From the Church to God
For I received from the Lord what I also delivered to you, that the Lord Jesus on the night when he was betrayed took bread, and when he had given thanks, he broke it, and said, “This is my body which is for you. Do this in remembrance of me.” In the same way also he took the cup, after supper, saying, “This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.” For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes.
(1 Corinthians 11:23-26 ESV)
3. INWARD: The Lord’s Supper is an Act of Church Union through Communion With Christ
The cup of blessing that we bless, is it not a participation in the blood of Christ? The bread that we break, is it not a participation in the body of Christ? Because there is one bread, we who are many are one body, for we all partake of the one bread.
(1 Corinthians 10:16-17 ESV)
4. OUTWARD: The Lord’s Supper is a Proclamation of the Gospel to an Unbelieving World
For I received from the Lord what I also delivered to you, that the Lord Jesus on the night when he was betrayed took bread, and when he had given thanks, he broke it, and said, “This is my body which is for you. Do this in remembrance of me.” In the same way also he took the cup, after supper, saying, “This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.” For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes.
(1 Corinthians 11:23-26 ESV)

The Decablog 
Particularly reveling in #3 lately as I have been meditating on the mind-blowing connection between Heb. 13:10, I Cor. 10:18, Lev. 16, Jn. 6:53-58 and I Cor. 11:24, 25 related to the significance of actually being a partaker of Christ’s sacrifice.
What a wonderful thing to revel in, Becky! If you haven’t already read it, you’d enjoy Rich Barcellos’s new book The Lord’s Supper as a Means of Grace. Here’s a link: http://www.rbap.net/our-books/the-lords-supper-as-a-means-of-grace-more-than-a-memory/
Thanks for the recommendation, Nick. Putting it on my list.
