New Defender's Study Bible Notes
11:25 This cup. In the observance of the Lord’s supper, the “cup” represents the New Covenant of God with His people, based on the shed blood of Christ offered in substitutionary sacrifice for our sins. The “cup,” with whatever contents it holds, is often used in Scripture to symbolize some great truth. For example, there is the cup of God’s wrath (Revelation 14:10), which is to be drunk by those who have previously imbibed the cup of Babylonian wickedness (Revelation 17:4). When Christ drank the bitter cup of sin’s wages for us (John 18:11), our own cup becomes a “cup of salvation” (Psalm 116:13) and “runneth over” (Psalm 23:5) with blessing.
