What are two reasons Jesus gave us the sacrament of the Eucharist?

It is recorded in the Bible that Jesus gave us the sacrament of the bread and the wine as a memorial, to remember His death it is a way to proclaim, make known His death until He comes again.

1Corinthians 11:25,26 In the same way, after the supper he took the cup and said, "This cup is God's new covenant, sealed with my blood. Whenever you drink it, do so in memory of me." This means that every time you eat this bread and drink from this cup you proclaim the Lord's death until he comes.
