What does the cup represent in the context of salvation?

In biblical terms, the cup represents both God's wrath and the blessings of salvation. In Isaiah 53:5, we read how He was 'wounded for our transgressions,' capturing the duality of Christ's fate. When He drank the cup, it was the full measure of God’s wrath against sin that He absorbed, effectively making that cup a representation of our salvation. For believers, what was originally a cup of fury and judgment transforms into a cup of blessing that signifies communion with Christ, as articulated in 1 Corinthians 10:16. Thus, the cup signifies a profound transition from judgment to acceptance in Christ.
